2023 Australian Open – Men's singles

Novak Djokovic defeated Stefanos Tsitsipas in the final, 6–3, 7–6(7–4), 7–6(7–5) to win the men's singles tennis title at the 2023 Australian Open. It was his record-extending 10th Australian Open title and 22nd major title overall, tying Rafael Nadal for the all-time record of most Grand Slam men's singles titles won. He also became the second man to win double-digit titles at a single major, after Nadal at the French Open. Djokovic lost just one set en route to the title (in the second round to Enzo Couacaud), and extended his match winning-streak at the Australian Open to an Open Era record 28 matches.

Nadal was the defending champion, but lost in the second round to Mackenzie McDonald.

Carlos Alcaraz, Casper Ruud, Tsitsipas and Djokovic were in contention for the world No. 1 singles ranking at the beginning of the tournament. By winning the tournament, Djokovic claimed the top spot. Alcaraz, the incumbent world No. 1, withdrew from the tournament due to a right leg injury.

As it was in the previous major held a few months earlier, neither of the top two seeds advanced to the quarterfinals, with Nadal and Ruud both losing in the second round; this marked the first men's singles major since the 2002 Australian Open where the top two seeds lost prior to the third round. Tsitsipas became the youngest finalist since Djokovic in 2011. Tommy Paul became the first American man to reach the semifinals since Andy Roddick in 2009.

With his win over Thanasi Kokkinakis in the longest match of his career, Andy Murray won a match from two sets down for a record eleventh time.
