Ground Zero: In Your House was the seventeenth In Your House professional wrestling pay-per-view event produced by the World Wrestling Federation (WWF) and presented by Stridex, which took place on September 7, 1997 at Louisville Gardens in Louisville, Kentucky. This was the first three-hour In Your House pay-per-view, and also the first that featured the "In Your House" name as the subtitle rather than the main title.

Seven professional wrestling matches were scheduled on the card. The main event saw Shawn Michaels and The Undertaker wrestle to a no contest. In another featured match, Bret Hart defeated The Patriot to retain the WWF World Heavyweight Championship. The Headbangers (Mosh and Thrasher) won the vacant WWF Tag Team Championship in a Four-Way Tag Team Elimination match and Brian Pillman defeated Goldust. Due to prior stipulations, Goldust's manager/wife (storyline and real-life) Marlena was required to become Pillman's personal assistant for 30 days.
