2024 Australian Open – Men's singles final

The 2024 Australian Open Men's Singles final was the championship tennis match of the men's singles tournament at the 2024 Australian Open, contested by fourth-seed Jannik Sinner and third-seed Daniil Medvedev. Sinner came back to defeat Medvedev from two-sets-to-love down, marking the second such loss for Medvedev in the Australian Open final after his defeat to Rafael Nadal in the 2022 final. It was Sinner's first major final. He became the second Italian man in the Open Era to win a singles major, after Adriano Panatta at the 1976 French Open, and the first new Australian Open champion in ten years, since Stan Wawrinka in 2014. At 22, Sinner was the youngest Australian Open men's singles champion and finalist since Novak Djokovic in 2008. This was the first Australian Open final since 2005 not to feature any of the Big Three members.

Medvedev set an Open Era record for the most time spent playing at a singles major, at 24 hours and 17 minutes. Medvedev also became the first player in the Open Era to lose two major finals after having a two-set lead.
