2015 Australian Open – Men's singles

Novak Djokovic defeated Andy Murray in the final, 7–6(7–5), 6–7(4–7), 6–3, 6–0 to win the men's singles tennis title at the 2015 Australian Open. It was his fifth Australian Open title and eighth major title overall. It was also Murray's fourth runner-up finish at the event, the most in the Open Era.

Stan Wawrinka was the defending champion, but lost in the semifinals to Djokovic. It was the third consecutive year that the two met at the Australian Open; on each occasion, their encounter went to a fifth set, and the victor of their match would go on to win the title.

Roger Federer's streak of eleven consecutive Australian Open semifinals ended when he lost to Andreas Seppi in the third round. The defeat marked Federer's earliest exit from the tournament since 2001.

Nick Kyrgios was the first teenager to reach the quarterfinals since Andrei Cherkasov in 1990, and the first Australian to do so since Lleyton Hewitt in 2005. He was the first teenager to reach multiple major quarterfinals since Rafael Nadal in 2006.
