# 2023 ATP Finals – Singles

Defending champion Novak Djokovic defeated Jannik Sinner in the final, 6–3, 6–3 to win the singles tennis title at the 2023 ATP Finals. It was his record-breaking seventh ATP Finals title, surpassing Roger Federer's achievement.
Djokovic also surpassed his own record as the oldest singles champion in the tournament's history, at 36 years old, and extended his record of the longest timespan between first and last Tour Finals titles won, at 15 years (the first being in 2008). Djokovic claimed the year-end No. 1 ranking for a record-extending eighth time after winning his first round-robin match; Carlos Alcaraz was also in contention for the year-end top spot.
Holger Rune and Alcaraz made their debuts at the event. Sinner made his debut as a direct qualifier, after playing two matches as an alternate in 2021.
