Si Jiahui (Chinese: 斯佳辉 sí-tɕjá-xwéɪ; born 11 July 2002) is a Chinese professional snooker player. After training at the Wiraka Billiard Academy in Foshan, he moved to the United Kingdom aged 16 and earned a two-year tour card through the 2019 Q School for the 2019–20 and 2020–21 seasons. He lost his tour card after ending the 2020–21 season outside the top 64 in the world rankings, and competed as an amateur during the 2021–22 season, during which he defeated Shaun Murphy 6–5 in the first round of the 2021 UK Championship. After rejoining the professional tour at the start of the 2022–23 season, he reached his first ranking quarter-final at the 2022 European Masters.
At the 2023 World Snooker Championship, Si won three qualifying matches to reach the tournament's final stages at the Crucible Theatre for the first time. He then defeated Murphy, Robert Milkins, and Anthony McGill as he progressed to the semi-finals, becoming the first Crucible debutant to reach the last four since Andy Hicks in 1995. Although he led 14–5 in the semi-final, he lost 15–17 to the eventual winner Luca Brecel; this nine-frame deficit was the largest lead overturned in the history of the World Championship. He advanced from 80th to 36th in the world rankings after the tournament. Si reached the first ranking final of his career at the following season's 2024 German Masters, but lost 5–10 to Judd Trump.
On 11 October 2024, Si achieved his first maximum break in professional competition in his 6–2 win against Judd Trump in the semi-final of the 2024 Wuhan Open.[2] Si would go on to lose the second ranking final of his career against Xiao Guodong.[3]
