Carlos Alcaraz defeated Novak Djokovic in the men's singles final at the Australian Open, winning 2–6, 6–2, 6–3, 7–5. The victory secured Alcaraz's first Australian Open title and made him the youngest man to complete a career Grand Slam.

Djokovic had not lost in any of his previous 10 Australian Open finals, but Alcaraz overcame a severe cramp from his prior match to dominate the final. He won 12 of the final 15 points in the second set to level the match.

Alcaraz broke Djokovic's serve in the third game of the third set and maintained control throughout. Djokovic committed 46 unforced errors, while Alcaraz used his athleticism to turn defense into offense.
