The 2023 ATP Masters 1000 season is the thirty-fourth edition of the ATP 1000 Series tennis tournaments. The champion of each ATP 1000 event is awarded 1,000 rankings points.
Beginning this year, the ATP 1000 events in Madrid, Rome, and Shanghai were expanded to two weeks in duration with a 96-player draw for singles.
Russian and Belarus players competed under no nationality due to the Russian invasion of Ukraine.
