2024 Australian Open – Men's singles

Jannik Sinner defeated Daniil Medvedev in the final, 3–6, 3–6, 6–4, 6–4, 6–3 to win the men's singles tennis title at the 2024 Australian Open. It was his first major singles title.

Sinner became both the first Italian to win the Australian Open and the second Italian man in the Open Era to win a singles major, after Adriano Panatta at the 1976 French Open. He was the first new Australian Open champion in 10 years. Medvedev lost the final after winning the first two sets (as he did in 2022), making him the only player in the Open Era to lose two major finals after having a two-set lead. Medvedev also set Open Era records for the most time spent playing at one edition of a singles major, at 24 hours and 17 minutes, and for the most sets played in a singles major, at 31.

Novak Djokovic was the defending champion, but lost in the semifinals to Sinner. His loss ended a 33-match winning streak at the Australian Open and marked his first-ever defeat in an Australian Open semifinal. Djokovic retained the world No. 1 singles ranking after Carlos Alcaraz lost in the quarterfinals.

A record number of seeded players (30 of 32 seeds) advanced to the second round, for the first time since the introduction of the 32-seed system at the 2001 Wimbledon Championships. A record-breaking opening round saw 20 matches extended to five sets, the most for the tournament since the start of the Open Era. The tournament overall featured a record-equaling 35 five-set matches, tying the Open Era record set at the 1983 US Open (surpassed soon after by the 2024 Wimbledon Championships).

This marked the final Australian Open and final major main draw appearance for 2020 finalist, 2020 US Open champion, and former world No. 3 Dominic Thiem, who later announced he would retire at the end of the 2024 season due to a chronic wrist injury. He lost to Félix Auger-Aliassime in the first round.
