Ding Liren (born 24 October 1992) is a Chinese chess grandmaster.
He is the highest rated Chinese chess player in history and is also a three-time Chinese Chess Champion.
He reached the finals of Chess World Cup in 2017 and 2019 consecutively, but ended up being the runner-up on both occasions.
Ding was undefeated in classical chess from August 2017 to November 2018, recording 29 victories and 71 draws.
