The 2017 Fastlane was the third Fastlane professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was held exclusively for wrestlers from the promotion's Raw brand division. The event took place on March 5, 2017, at the Bradley Center in Milwaukee, Wisconsin. This was the first Fastlane event to be brand exclusive, following the reintroduction of the brand split in July 2016, and the first non-WrestleMania WWE pay-per-view to take place in March. This was also WWE's last pay-per-view event to take place at the Bradley Center before its closure in 2018 with future WWE events in Milwaukee held at Fiserv Forum.

Ten matches were contested at the event, including one on the Kickoff pre-show. In the main event, Goldberg defeated Kevin Owens to win the WWE Universal Championship, becoming the only person to win the Universal Championship, WWE's World Heavyweight Championship, and the WCW World Heavyweight Championship. In other prominent matches, Roman Reigns defeated Braun Strowman, ending Strowman's undefeated streak, Bayley retained the Raw Women's Championship against Charlotte Flair, thus ending Flair's undefeated streak in singles matches at pay-per-views, Neville retained the WWE Cruiserweight Championship against Gentleman Jack Gallagher, and Luke Gallows and Karl Anderson retained the Raw Tag Team Championship against Enzo Amore and Big Cass.
