A nickname is a descriptive name given in place of or in addition to the actual name of a person. As in many sports, in snooker many players have nicknames.

This is a list of common nicknames for notable professional snooker players.

Ronald Antonio "Ronnie" O'Sullivan (born 5 December 1975) is an English professional snooker player known for his rapid playing style, and is nicknamed "The Rocket". He has been World Champion on four occasions (2001, 2004, 2008 and 2012) and, with career earnings of over £6 million is second after Stephen Hendry on snooker's all-time prize-money list. O'Sullivan has been the world's no. 1 player on five occasions, and has won a total of 24 ranking titles. He is second, again behind Hendry, on the list of players making the most competitive century breaks, with a total of 678. O'Sullivan has compiled 11 maximum breaks in professional competition, a record which he shares with Hendry. He also holds the record for the fastest maximum break, at 5 minutes 20 seconds.

O'Sullivan is considered by many fans, critics and professionals, including fellow multiple-World Championship winners Hendry and Steve Davis, as the most naturally talented player in the history of the game. He has, however, been involved in a number of controversial incidents during his career.

Liu Chuang (Chinese: 刘闯, pinyin: Liú Chuǎng) (born 6 June 1990) is a Chinese professional snooker player.

Liu grew up in Liaoning province in northeast China. Near his parents' house there was a snooker table and when he was 10 he played on it and liked it a lot. His father noticed his potential, and supported him as did the person who owned that table, who became his first coach.

When he was 13 Liu, travelled thousands of miles to play in southern China, where there were more professionals. There he improved and began to play competitive matches. In 2007, the chairman of the Asian Snooker Association saw his potential, and he gained a wild card in the China Open.

In 2005, Liu was a runner-up in a national junior tournament in China. In 2006, Liu reached the final of a senior national tournament.

Liu first came to the attention of the snooker world when he was picked as a wildcard to enter the 2007 China Open. Liu was victorious over Andy Hicks, beating him 5–4. That set up a meeting with Liu's idol,Ronnie O'Sullivan; Liu lost the match 1–5.

Liang Wenbo (Chinese: 梁文博, pinyin: Liáng Wénbó ; born 5 March 1987 in Zhaodong, Suihua, Heilongjiang) is a Chinese professional snooker player. He is left-handed and ranked as China's number 2 player, after Ding Junhui. Liang is based at the Grove Snooker Academy in Romford, England, United Kingdom.

As an amateur, Liang's major feats were as follows:

Liang built on the positive start to his snooker career, winning an individual silver medal and a team gold medal at the 2006 Asian Games.

During the 2004/05 snooker season, Liang took part in the Challenge Tour, the tier below the World Snooker Association Main Tour. He finished a lowly 104th out of 168 competitors, having only accumulated 2150 points.

Despite not qualifying for the main snooker tour directly, Liang received a wildcard nomination to the main tour; this was because he won the 2005 IBSF World Under-21 Championship and because not all the players that were eligible for the main tour took their places. In his first ranking tournament, the Grand Prix, Liang lost in the first qualifying round to Rory McLeod 2–5. In the next ranking event, the UK Championship, he fared better, nearly whitewashing Alfred Burden in the first qualifying round 9–1; he lost in the second qualifying round to Marcus Campbell by the narrowest of margins, 8–9.

Allister "Ali" Carter (born 25 July 1979, Colchester, Essex, England) is an English professional snooker player, who lives in Chelmsford. He is a two-time World Championship runner-up, twice losing to Ronnie O'Sullivan in 2008 and 2012. He has also won two ranking titles and been as high as second in the world rankings.

Carter turned professional in 1996. He first emerged in 1999, winning the WPBSA Association Young Player of the Year award after winning the Benson and Hedges Championship in 1999 – this earned him a wild card place in the Masters. He also reached the semi-finals of the 1999 Grand Prix. It was eight years before he reached another ranking semi-final, the 2007 Malta Cup.

He was close to the elite top 16 for three successive seasons ranking as 17, 19, and 19 through 2003/04, 2004/05 and 2005/06, respectively, before reaching it in the 2006/07 season and remaining there in 2008.

He reached the last 16 (second round) of the World Championship in 2005, after scoring the first 10–0 victory in the event since 1993 against 1993 semi-finalist James Wattana in qualifying. At the 2007 World Championship he beat Andy Hicks in the first round, 10–4, before beating World No. 1 and seven-time champion Stephen Hendry 13–6 to reach his first World Championship quarter-final and guarantee a place in the Top-16. Carter now has a 5–4 record against Hendry; conversely, he has never beaten Ronnie O'Sullivan in 12 attempts.
