The 2017–18 snooker season was a series of professional snooker tournaments played between 4 May 2017 and 7 May 2018. The season began with the pro–am Vienna Snooker Open in May 2017 and ended with the 2018 World Snooker Championship in April the following year. Ronnie O'Sullivan earned a joint-record five ranking titles in the season. He joined Stephen Hendry (1990/1991), Ding Junhui (2013/2014), and Mark Selby (2016/2017) in winning five ranking titles in the same season.
The China Championship became a ranking event and was brought forward to a mid-August date, ahead of the Paul Hunter Classic. The Shanghai Masters was initially withdrawn from the season calendar, but was later rescheduled for November 2017. The biennial World Cup team event was played in July 2017. Another event not held every year returning in 2017 was the 2017 IWGA World Games. The Snooker Shoot Out was brought forward to the start of February, ahead of both the World Grand Prix and Welsh Open.
The second edition of the Home Nations Series was being held in this season with the English Open, Northern Ireland Open, Scottish Open and Welsh Open tournaments. For a single winner of all four tournaments would earn a bonus of £1 million. 13 different countries and/or regions have held at least one tournament on the main tour during the season, making it one of the most diverse season calendars since the takeover of World Snooker by Matchroom Sport.
A new World Seniors Tour was formed by Snooker Legends for players over 40 years of age, comprising four events, including the World Seniors Championship which has returned to Scunthorpe in 2018.
Ronnie O'Sullivan won five ranking events during the season, with Mark Williams winning three times and Ryan Day, John Higgins and Mark Selby each winning twice. Shaun Murphy reached four ranking event finals during the season but lost them all.
