Fully Loaded: In Your House was the 23rd In Your House and inaugural Fully Loaded professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF; WWE as of 2002). It took place on July 26, 1998, at the Selland Arena in Fresno, California. Nine matches were contested at the event.

The main event was a tag team match for the WWF Tag Team Championship. Kane and Mankind put the title on the line against The Undertaker and Stone Cold Steve Austin, who was the reigning WWF Champion. Undertaker and Austin won when Undertaker pinned Kane after a Tombstone.

The undercard featured Jacqueline versus Sable in a bikini contest, The Rock versus Triple H in a two of three falls match for the WWF Intercontinental Championship, Owen Hart versus Ken Shamrock in a Dungeon match, Disciples of Apocalypse (8-Ball and Skull) versus L.O.D. 2000 (Hawk and Animal), Mark Henry versus Vader, Faarooq and Scorpio versus Terry Funk and Bradshaw, D'Lo Brown versus X-Pac, and Val Venis versus Jeff Jarrett.

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). Fully Loaded returned in July 1999, becoming the promotion's annual July PPV; however, it was a short-lived event as the final event was held in July 2000.
