Twenty-four time Grand Slam champion Novak Djokovic closed the 2023 ATP season by clinching the year-end No. 1 spot for a record-extending eighth time.

Djokovic won three of the four Grand Slam tournaments, including the Australian Open in January, the French Open in June, and the US Open in July. In September, he won the US Open to bring his career total to a men's-record 24, and he finished second at Wimbledon.
