The 2017 Hell in a Cell was the ninth annual Hell in a Cell professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was held exclusively for wrestlers from the promotion's SmackDown brand division. The event took place on October 8, 2017, at Little Caesars Arena in Detroit, Michigan.

Eight matches were contested at the event, including one on the Kickoff pre-show, and the main card featured two bouts in the titular match type. In the main event, Kevin Owens defeated Shane McMahon in the namesake match that also had the added stipulation of falls count anywhere. In the other Hell in a Cell match, which was the opening bout, The Usos (Jey Uso and Jimmy Uso) defeated The New Day (represented by Big E and Xavier Woods) to become record three-time SmackDown Tag Team Champions. It was also the first time that a WWE tag team championship was defended in a Hell in a Cell match. Other prominent matches included Jinder Mahal retaining the WWE Championship against Shinsuke Nakamura, and Baron Corbin defeated defending champion AJ Styles and Tye Dillinger to win the United States Championship in an impromptu triple threat match. The event was also notable for Bobby Roode's main roster pay-per-view debut where he defeated Dolph Ziggler.
