The 2017–18 World Rugby Sevens Series, known for sponsorship reasons as the HSBC World Rugby Sevens Series, was the 19th annual series of rugby sevens tournaments for national men's rugby sevens teams. The Sevens Series has been run by World Rugby since 1999–2000.
The Paris and London Sevens, which swapped places in the season order, will take place several weeks later than usual in order to provide more rest for players, many of whom will have been involved in the Commonwealth Games.
