Novak Djokovic won a record-extending 10th Australian Open and a record-equalling 22nd Grand Slam men’s title.
Djokovic won 6-3 7-6 (7-4) 7-6 (7-5) against Stefanos Tsitsipas in Melbourne.
He dropped just one set all tournament despite saying he feared a left hamstring problem might force him to withdraw.
Djokovic is the fifth player to win 22 Grand Slam singles titles, after Margaret Court (24), Serena Williams (23), and Steffi Graf and Nadal (both 22).
He reclaims the world No 1 ranking from Carlos Alcaraz.
Djokovic was overcome with emotion after climbing into the stands to celebrate with his family.
He lay down in the player box sobbing uncontrollably before recomposing himself for the presentation ceremony.
He said: “This has been one of the most challenging tournaments I’ve ever played in my life. Not playing last year, coming back this year. I want to thank all the people that made me feel welcome, made me feel comfortable to be in Melbourne, to be in Australia.
“There’s a reason I’ve played my best tennis on this court. Only my team and my family know what we’ve been through in the last four, five weeks. This probably is the biggest victory in my life considering the circumstances.”
With the heavy strapping on his left hamstring missing for the first time all tournament, Djokovic hit top form straight away at the Rod Laver Arena, winning the first set in 36 minutes.
Tsitsipas, appearing in his first final in Melbourne, was forced to save two break points in his first service game but came unstuck two games later.

The 24-year-old said: “Novak I don’t know what to say, I think it speaks for itself what you have achieved so far. Congratulations. I admire what you have done for our sport, I think you make me a better player.
“I’ve had the privilege to play a lot of high-intensity matches. These are the matches I’ve been working my entire life for. I’d like to thank you for pushing our sport so far.
“It’s not easy. Another final at a Grand Slam but I’m always willing to go back on court and work harder.”
