Ma Long (; born 20 October 1988) is a Chinese table tennis player. Commonly regarded as the greatest table tennis player of all time, he is the first male player to complete a career Double Grand Slam as the Olympic gold medalist in men's singles in 2016 and 2020. He held the ranking of number 1 for a total of 64 months (and 34 consecutive months from March 2015), the most by any male in the history of table tennis. He is also champion in World Championships in men's singles in 2015, 2017 and 2019. His records led the International Table Tennis Federation to nickname him as "The Dictator" and "The Dragon" (derived from his name, Lóng, which represents the zodiac year of his birth). Since 2014, he has been the captain of the Chinese national table tennis men's team.
