D-Generation X: In Your House (also spelled as Degeneration X: In Your House) was the 19th In Your House professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE). It took place on December 7, 1997, at the Springfield Civic Center in Springfield, Massachusetts, and was the fifth, and final WWF pay-per-view to be sponsored by Milton Bradley's Karate Fighters. Eight matches were contested at the event.

In the main event, Ken Shamrock defeated Shawn Michaels by disqualification in a match for the WWF Championship; Michaels thus retained his title. Notable matches on the undercard included "Stone Cold" Steve Austin defeating The Rock to retain the WWF Intercontinental Championship, The New Age Outlaws defeating the Legion of Doom by disqualification to retain the WWF Tag Team Championship, and WWF Commissioner Sgt. Slaughter coming out of retirement to lose a Boot Camp match to Triple H.
