The 2017 Extreme Rules was the ninth annual Extreme Rules 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 June 4, 2017, at the Royal Farms Arena in Baltimore, Maryland, and was the second Extreme Rules held at this venue after the 2010 event, when it was formerly known as 1st Mariner Arena; the arena changed its name to Royal Farms Arena in 2014. It was also the only brand-exclusive Extreme Rules event to be held during either of WWE's brand extension periods. The concept of Extreme Rules is that the event features various hardcore-based matches.

Seven matches were contested at the event, including one on the Kickoff pre-show. Only three of the main card's matches were contested under a hardcore stipulation. In the main event, Samoa Joe defeated Roman Reigns, Seth Rollins, Finn Bálor, and Bray Wyatt in an Extreme Rules fatal five-way match to earn a Universal Championship match at Great Balls of Fire. In other prominent matches, Cesaro and Sheamus defeated The Hardy Boyz (Jeff Hardy and Matt Hardy) in a Steel Cage match to win their second Raw Tag Team Championship as a team, and in the opening bout, The Miz defeated Dean Ambrose to win his seventh Intercontinental Championship.
