Judgment Day: In Your House

Judgment Day: In Your House was the 25th In Your House and inaugural Judgment Day professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF; WWE as of 2002). It took place on October 18, 1998, at the Rosemont Horizon in the Chicago suburb of Rosemont, Illinois. Nine professional wrestling matches were scheduled on the event's card.

The main event saw The Undertaker and Kane fighting each other, despite their alliance at the time, for the WWF Championship which was vacant at the time after company owner Vince McMahon stripped former champion "Stone Cold" Steve Austin to further the storyline. Austin was made special guest referee for the match, a role he was not keen to accept. The card included four other championship matches. All WWF championships except the WWF Women's Championship, which had been reinstated only a month before, were contested at the event.

This was one of the In Your House events which later became the title of an annual pay-per-view, replacing the method at the time of making new names for all events aside from the "Big Five" (Royal Rumble, WrestleMania, King of the Ring, SummerSlam, and Survivor Series). Judgment Day returned in May 2000, becoming the promotion's annual May PPV until its final event in 2009.
