2022 Australian Open – Men's singles
Rafael Nadal defeated Daniil Medvedev in the final, 2–6, 6–7, 6–4, 6–4, 7–5 to win the men's singles tennis title at the 2022 Australian Open. It was his second Australian Open title and 21st major singles title overall, surpassing the all-time record he had jointly held with Novak Djokovic and Roger Federer. Nadal became the fourth man, after Djokovic, Roy Emerson, and Rod Laver, to achieve the double career Grand Slam, and the second in the Open Era, joining Djokovic. He also became the first man in the Open Era to win  an Australian Open final after losing the first two sets. Djokovic was the three-time defending champion, but he was unable to compete after his visa was cancelled shortly before the tournament began due to an intervention from Australia's Immigration Minister Alex Hawke, citing risks to public health and good order in Australia. This meant Nadal was the only former champion (2009) to compete in the tournament, with both Federer and Stan Wawrinka sidelined by injury. Djokovic retained the ATP No. 1 singles ranking despite being unable to defend his points after Medvedev and Alexander Zverev lost in the  final and fourth round, respectively. Matteo Berrettini became the first man born in the 1990s to reach the quarterfinals at all four majors in singles, and the first Italian man to reach the semifinals of the Australian Open.

The following players would have been seeded, but withdrew before the tournament began. Djokovic visa controversy. Djokovic lost his ability to compete when his visa to  enter Australia was cancelled. Despite being granted a medical exemption to the tournament's COVID-19 vaccine requirement by Tennis Australia, the Australian Border Force confirmed that after being detained at Melbourne Airport for eight hours, Djokovic's visa had been cancelled and he would be denied entry to the country due to not meeting exemption criteria to Australia's vaccination requirements. Djokovic sought an injunction to prevent his deportation. The Federal Circuit and Family Court ruled in favour of Djokovic, ordered his release from detention and directed the federal government to pay his legal expenses. On 14 January Minister for  Immigration Alex Hawke used his discretionary power to cancel Djokovic's visa on health and good order grounds. Djokovic sought a judicial review against deportation, but three Federal Court of Australia judges unanimously rejected the review on 16 January, preventing him from defending his title.
