The 1999 Fully Loaded was the second annual Fully Loaded professional wrestling pay-per-view (PPV) event produced by the World Wrestling Federation (WWF, now WWE). It took place on July 25, 1999, at the Marine Midland Arena in Buffalo, New York. Although the event was the second Fully Loaded PPV held, it was the first Fully Loaded not held under the In Your House series, which had been discontinued in February 1999. Matches at the event were fought in a number of venues, including a parking garage.

The main event was a First Blood match for the WWF Championship. Stone Cold Steve Austin defeated The Undertaker to retain the title by hitting him with a television camera and causing him to bleed after interference by X-Pac. The match stipulated that if The Undertaker won, Austin would never wrestle for the WWF Championship ever again, but if Austin won, the WWF Chairman Vince McMahon could never appear on WWF television.

The undercard featured Triple H versus The Rock in a strap match, Road Dogg and X-Pac versus Billy Gunn and Chyna in a tag team for the rights to win the D-Generation X name, Ken Shamrock versus Steve Blackman in an Iron Circle match, Big Show versus Kane, Al Snow versus Big Boss Man for the WWF Hardcore Championship, Mideon versus D'Lo Brown for the WWF European Championship, Hardy Boyz (Matt Hardy and Jeff Hardy) and Michael Hayes versus The Acolytes (Faarooq and Bradshaw) in a Handicap match for the WWF Tag Team Championship and Edge versus Jeff Jarrett for the WWF Intercontinental Championship.
