2026 Australian Open – Men's singles
Carlos Alcaraz defeated Novak Djokovic in the final, 2–6, 6–2, 6–3, 7–5 to win the men's singles tennis title at the 2026 Australian Open. It was his first Australian Open title and seventh major title overall, becoming the youngest man in tennis history to complete the career Grand Slam in singles. He was also the youngest man in the Open Era to reach the singles final of all four majors. The final was a rematch of the previous year's quarterfinal match, won by Djokovic. With the win, Alcaraz ended Djokovic's unbeaten 10–0 record in Australian Open finals.
Jannik Sinner was the two-time defending champion, but lost in the semifinals to Djokovic in a rematch of their semifinal match two years prior. Sinner's loss ended his streak of five consecutive major finals, dating to the 2024 US Open.
At 38 years and 255 days old, Djokovic became the oldest man in history to reach the Australian Open final, and the oldest major finalist overall since Ken Rosewall at the 1974 US Open. By making his 81st career major appearance, he equaled Roger Federer and Feliciano López's joint all-time record for the most total major main draw appearances, and equaled Federer's record 21 Australian Open main draw appearances. With his quarterfinal win, he recorded his 103rd Australian Open match win, breaking Federer's record for most match wins at the Australian Open.
At 5 hours and 27 minutes long, the semifinal between Alcaraz and Alexander Zverev was the longest Australian Open semifinal, and third-longest overall match in tournament history. Valentin Vacherot became the first Monégasque singles player to reach the third round of a major in the Open Era. Learner Tien was the youngest player to reach the Australian Open quarterfinals since Nick Kyrgios in 2015.
For the first time in the Open Era, and first time since the 32-seed system was introduced at the 2001 Wimbledon Championships, all the players who reached the fourth round at a major were seeded. For the first time in the Open Era, the top six seeds reached the quarterfinals in both the men's and women's singles competitions. This was also the first time since the 2019 French Open that the top four men's seeds all reached the semifinals of a major, and the first such occurrence at the Australian Open since 2013.
The tournament marked the final Australian Open appearance of 2014 champion, three-time major champion, and former world No. 3 Stan Wawrinka; he lost in the third round to Taylor Fritz. At 40 years and 296 days old, Wawrinka was the oldest player to reach the third round of a major since Rosewall at the 1978 Australian Open. His second-round win marked his 58th five-set match, tied with Ivan Lendl for the most by any player in the Open Era.
