Ude-Hishigi-Waki-Gatame (Japanese: 腕挫腋固) is an armlock and one of the official 29 grappling techniques of Kodokan Judo. It is one of the nine joint techniques of the Kansetsu-waza list, one of the three grappling lists in Judo's Katame-waza enumerating 29 grappling techniques. 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.

This armlock is executed with Uke on their stomach, while tori has uke's arm trapped with the elbow beneath tori's armpit. 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. He applied it on Keith Wisniewski during a clinch exchange, breaking his arm.^[1]
