Bjorn Borg was born in Stockholm, Sweden, on 6 June 1956, as the only child of Rune and Margaretha Borg. He grew up in nearby Sodertalje. As a child, Borg became fascinated with a golden tennis racket that his father won at a table-tennis tournament. His father gave him the racket, beginning his tennis career.

Borg won his last Grand Slam title at the French Open in 1981, defeating Lendl in a five-set final. Borg's six French Open Grand Slam titles was a record bettered only by Rafael Nadal in 2012. In reaching the Wimbledon final in 1981, Borg stretched his winning streak at the All England Club to a record 41 matches. In a semifinal, Borg was down to Connors by two sets to love, before coming back to win the match. However, Borg's streak was brought to an end by McEnroe, who defeated him in four sets. Years afterward, Borg remarked "And when I lost what shocked me was I wasn't even upset. That was not me: losing a Wimbledon final and not upset. I hate to lose." Borg around that time felt that his desire to play was gone, despite McEnroe's desperate efforts to persuade him not to retire and continue their rivalry. Borg went on to lose to McEnroe at the 1981 US Open. After that defeat, Borg walked off the court and out of the stadium before the ceremonies and press conference had begun, and headed straight for the airport. There are reports that Borg received threats after his semifinal win over Connors. In later years, Borg apologized to McEnroe. The 1981 US Open would be the Swede's last Grand Slam final. Major tournaments and tour organizers were enforcing a new rule; by 1982, that players had to play at least 10 official tournaments per year. However, Borg wanted to curtail his schedule after many years of winning so often. Although he felt in good condition physically, he recognized that the relentless drive to win and defy tour organizers had begun to fade. Borg failed to win the US Open in 10 tries, losing four finals, 1976 and 1978 to Jimmy Connors, and 1980 and 1981 to McEnroe. He played on hard courts at the US Open from 1978 to 1981 and reached the final there on three occasions, in 1978, 1980 and 1981. He led 3-2 in the fifth set of the 1980 final, before losing. That match followed Borg's classic encounter with McEnroe at the 1980 Wimbledon. In 1978, 1979 and 1980, Borg was halfway to a Grand Slam after victories at the French and Wimbledon (the Australian Open being the last Grand Slam tournament of each year at the time) only to falter at Flushing Meadow, lefty Tanner his conqueror in 1979. In 1982, Borg played only one tournament, losing to Yannick Noah in the quarterfinals of Monte Carlo in April. Nevertheless, Borg's announcement in January 1983 that he was retiring from the game at the age of 26 was a shock to the tennis world. McEnroe tried unsuccessfully to persuade Borg to continue. He did, however, play Monte Carlo again in March 1983, reaching the second round, and Stuttgart in July 1984.
