Ude-Hishigi-Waki-Gatame (Japanese: 腕挫腋固) is an armlock and one of the official 29 grappling techniques of Kodokan Judo.

Falling directly to the mat while applying or attempting to apply the Waki gatame in competition is listed as an hansoku make (反則負け; literally "foul-play loss") by the International Judo Federation.

It is known as Fujiwara armbar in professional wrestling and occasionally in mixed martial arts.

Tori lifts uke's hand, causing hyperextension of the elbow joint in a similar manner to Ude-Hishigi-Juji-Gatame.

The move was successfully used in mixed martial arts by Shinya Aoki in his debut on Shooto on January 25, 2005.
