In doubles, Mladenovic and Garcia, once again the No. 1 seeds, made their way to the final, in which they faced Mattek-Sands and Šafářová, in a rematch of the US Open final a few weeks earlier.

### 2017: First WTA Tour singles title and top-10 singles debut

Mladenovic began the year by playing at the Hopman Cup alongside Richard Gasquet. The pair won their first tie against Germany's Andrea Petkovic and Alexander Zverev 2–1 (Mladenovic lost her singles match against Petkovic), and their second tie against Great Britain's Dan Evans and Heather Watson 3–0. In France's third Group A tie against Switzerland which would decide which team would enter the final, Mladenovic (following Gasquet's defeat to Roger Federer) defeated Belinda Bencic and triumphed with Gasquet against the Swiss pair in mixed doubles, winning the tie 2–1. In the final, Mladenovic and Gasquet faced Americans Jack Sock and CoCo Vandeweghe. Although Gasquet won his singles match and Mladenovic lost hers, the French duo won the decisive mixed-doubles match, meaning that France were the 2017 Hopman Cup champions.
Mladenovic had a disappointing run at the Australian Open in singles, losing in the first round to Ana Konjuh. However, in doubles, reunited with partner Caroline Garcia, she reached the semifinals of the event, where they lost to Andrea Hlaváčková and Peng Shuai. At the St. Petersburg Ladies' Trophy, Mladenovic won her first round match against Elise Mertens before upsetting reigning Australian Open finalist Venus Williams to reach the quarterfinals. She continued her fabulous form against No. 6 seed and defending champion Roberta Vinci, defeating the Italian veteran in straight sets. In the semifinals, the French woman defeated rising player Natalia Vikhlyantseva to reach the first WTA Premier singles final of her career. In a tense final, Mladenovic defeated Yulia Putintseva, 6–2, 6–7, 6–4 to win the first WTA Tour singles title of her career. Mladenovic became the first French woman to win a WTA Premier singles title since Marion Bartoli in Eastbourne in June 2011. In addition, Mladenovic competed in doubles with Daria Gavrilova (this was the first time Mladenovic played with someone other than Garcia in over a year) but the pair were defeated in the semifinals.
In the Fed Cup World Group quarterfinals against Switzerland, Mladenovic won her first singles match against Belinda Bencic. However, she then lost to Timea Bacsinszky in her next singles match. France lost the tie 1–4, resulting in France needing to win the Fed Cup World Group Play-off tie to earn the right to play in the 2018 World Group.
At Dubai, at the first Premier-5 event of the season, Mladenovic defeated Kateřina Siniaková in the first round before defeating world No. 3, Karolína Plíšková, 6–2, 6–4 in the second round. She then lost to Wang Qiang in the third round. Mladenovic's good form continued at the Mexican Open, where she stormed past Varvara Lepchenko before winning a marathon match against Heather Watson to reach the quarterfinals, in which she defeated Kirsten Flipkens. Mladenovic then won her semifinal encounter with Christina McHale, reaching her second WTA Tour singles final of 2017. Though she did end up losing to Lesia Tsurenko in the final, her success in February allowed Mladenovic to reach a career-high WTA singles ranking of No. 26. Moreover, Mladenovic was nominated for February's WTA Shot of the Month, WTA Breakthrough Player of the Month, and WTA Player of the Month (winning the WTA Breakthrough Player of the Month).
Prior to the Indian Wells Open, Mladenovic announced that her doubles partnership with Caroline Garcia would end because Garcia wanted to focus on her singles career. Mladenovic instead competed with Svetlana Kuznetsova in the doubles draw of Indian Wells. Meanwhile, in singles, the French woman received a bye into the second round, being seeded No. 28. She had a strong opening, defeating Annika Beck of Germany. In the third round, Mladenovic continued her newfound success by defeating world No. 4, Simona Halep, in straight sets, setting up an encounter with Lauren Davis, which she won in straight sets as well, reaching her first career Premier Mandatory singles quarterfinals. Mladenovic continued to shine, defeating Caroline Wozniacki 3–6, 7–6, 6–2 (Mladenovic had never beaten Wozniacki in three previous encounters) before losing to eventual champion Elena Vesnina in the semifinals. Her good performance at Indian Wells enabled Mladenovic to attain a career-high singles ranking of No. 18, and she became the No. 1 French woman once again (passing Caroline Garcia). She also had success with Kuznetsova in the doubles, knocking out the fifth-seeded pair of Andrea Hlaváčková and Peng Shuai in the second round before losing in the quarterfinals.
At the Miami Open, Mladenovic lost her opening singles match to the Romanian qualifier Patricia Maria Țig. In doubles, playing again with Kuznetsova, she faced Hlaváčková and Peng in the quarterfinals, in a repeat of their Indian Wells encounter. This time, Hlaváčková and Peng won the match, and Mladenovic missed the opportunity to become doubles world No. 1.
At the Porsche Tennis Grand Prix, Mladenovic defeated top-seed Angelique Kerber in the second round and three-time champion Maria Sharapova (who was playing her first WTA tournament after serving a 15-month suspension for failing a drug test) in the semifinals to reach her third WTA Tour singles final of the year. Against German wildcard Laura Siegemund (who was playing in her hometown), Mladenovic led 4–1 in the final set tiebreak but ended losing the match 1–6, 6–2, 6–7.
Mladenovic, seeded No. 14, reached her first career Premier Mandatory singles final at the Madrid Open by defeating her doubles partner Svetlana Kuznetsova in the semifinals. In the final, she lost to third seeded Simona Halep in three sets. On 15 May (the day after the Madrid final), Mladenovic reached a career-high WTA singles ranking of No. 14. Seeded No. 13, Mladenovic lost her singles first round match against Julia Görges at the Italian Open. At her home Grand Slam, the French Open, she won her first-round match in a tight three sets against American Jennifer Brady. In the second round, she faced the 2012 finalist Sara Errani whom she defeated in straight sets. In the third round, she had a close match against Shelby Rogers and advanced to the fourth round, her best showing at this tournament. She defeated the fourth seed and defending champion Garbiñe Muguruza in three sets to advance to her second quarterfinal of a Grand Slam tournament in her career. She then lost to Timea Bacsinszky.
Her form declined in the second half of the season. At Wimbledon, she lost in the singles second round, sustaining a right knee injury in the process. Over the next four months, she struggled to get back into shape again and suffered a loss of confidence. This caused Mladenovic to lose all twelve of her remaining singles matches of 2018 after winning her first-round singles match at the Washington Open (she won only two sets in those 12 singles matches) at various hard-court tournaments (including the US Open) in North America, Asia and Europe. Arguably her worst moment came at the Pan Pacific Open, where she suffered a double bagel defeat in the first round against Wang Qiang.
However, due to a consistent first half of the season which saw Mladenovic being constantly in the top eight of the Race to Singapore, she eventually broke into the top ten of the singles rankings for the first time in her career (at No. 10) on 23 October 2017, at the start of the WTA Finals. And because of big results in that half of the season, Mladenovic called the season "still the best of my career", when opening about her singles slump in the second half of the year.

### 2018: Australian Open doubles title

Mladenovic started her season at the Brisbane International, where she lost in the first round to the eventual singles finalist Aliaksandra Sasnovich in three sets. In her next tournament, the Sydney International, she retired in second set of her first-round match against the Australian wildcard Ellen Perez due to heat stress. At the Australian Open, Mladenovic's poor form in singles continued, losing her first round match in straight sets to world No. 104, Ana Bogdan from Romania, extending her losing streak in singles to 15 consecutive matches. Opening up about the loss, Mladenovic stated that it was not about injury anymore, that it was just a bad day and that it could not continue like that. Mladenovic turned things around when she won the Australian Open women's doubles with Tímea Babos, thus winning her second career Grand Slam women's doubles title.
Mladenovic next played in St. Petersburg as the defending singles champion. After receiving a first-round bye, Mladenovic showed signs of her top form and confidence which enabled her to reach four WTA singles finals in the first half of 2017 by defeating former top-5 player and 2016 WTA Finals champion Dominika Cibulková in the second round, ending her 15-match losing streak in singles. She then followed up her second round win by beating Kateřina Siniaková in the quarterfinals and Daria Kasatkina in the semifinals (who had beaten the 2018 Australian Open champion Caroline Wozniacki previously), to advance to her first WTA Tour singles final since the Madrid Open the previous year. In the final, she lost to Petra Kvitová in straight sets. Mladenovic won both her singles matches and her doubles match in the Fed Cup World Group quarterfinal tie against Belgium on February 10–11.

At the French Open, the 29th seeded Mladenovic lost in the singles first round to Andrea Petkovic. Mladenovic and Babos were the women's doubles top seeds at that tournament, losing in the quarterfinals to the unseeded Japanese pair of Eri Hozumi and Makoto Ninomiya. On 11 June, Mladenovic's WTA singles ranking fell to world No. 54, compared to No. 31 two weeks earlier. She played her first grass-court tournament of the year in Birmingham, where she lost in the singles second round to the unseeded Magdaléna Rybáriková. Mladenovic and Babos won the Birmingham title defeating Elise Mertens and Demi Schuurs in the final. The following week in Eastbourne, the again unseeded Mladenovic lost in the singles second round to the No. 8 seed Ashleigh Barty. The unseeded Mladenovic was defeated in the third round of Wimbledon by Serena Williams in two sets, and the top-seeded pair of Mladenovic and Babos were eliminated in the quarterfinals.

Playing with Veronika Erjavec, Mladenovic won the doubles title at the 2024 WTA 125 Cali Open, defeating Tara Würth and Katarina Zavatska in the final.

## Playing style

Mladenovic employs an all-court playing style, using variety along with her baseline play to win points. Her forehand is her strongest wing, and she is capable of hitting this shot both flat, and with topspin. Her backhand is also a solid shot, and she is capable of hitting her two-hander consistently and can hit backhand winners frequently; she does tend to utilise her sliced backhand more frequently to change the pace of the rally. She possesses a powerful serve, and her height of 1.84 m (6 ft 1⁄2 in) means that serve aces frequently; this is aided by the fact that her first serve peaks at 116 mph (187 km/h). However, her second serve is much weaker, and she can serve many double faults in a match; during her first round loss to Ekaterina Alexandrova at 2020 Palermo, Mladenovic served 20 double faults. Her doubles success in recent years has allowed her to develop a strong net game; she has begun to approach the net to finish points in singles more frequently due to her increased confidence. She uses her volleys, along with her backhand slice and drop shots, to create a lot of variety in her game. Her movement around the court is very good, considering her height and her footwork, but this can be exposed as a weakness when she needs to recover. Mladenovic's greatest weakness is her fragile mentality, as she finds it difficult to cope with pressure, committing myriad unforced errors, and can lose matches from winning positions – in her second round match at the 2020 US Open, she was leading by 6–1, 5–1 against Varvara Gracheva, holding four match points, before losing in three sets.

Notes
* ↑ Babos and Mladenovic were forced to withdraw before second-round match due to Mladenovic being in contact with Benoît Paire who was tested positive for COVID-19, despite Mladenovic being tested negative multiple times. Their walkover in the second round is not counted as loss.
