OG 82 was an Allied convoy of the OG (Outward to Gibraltar) series during World War II. The action involving this convoy resulted in the destruction of a U-boat, and also had consequences for German U-boat strategy.

OG 82 comprised 17 ships outward bound to Gibraltar, carrying war materials and trade goods. The convoy commodore was Captain AJ Baxter in Baron Yarborough, and the convoy was protected by an understrength escort group. This was 36th Escort Group, led by Cdr FJ "Johnnie" Walker, consisting of the sloop Stork and the Flower-class corvettes Convolvulus, Penstemon, Vetch and Gardenia (joined 13 April). The convoy's protection was enhanced by armed merchants— the CAM ships Empire Eve and Empire Heath, and the rescue ship Toward.

OG 82 left Liverpool on 8 April 1942. On 14 April 1942 OG 82 was at the western edge of the Bay of Biscay when it was encountered by U-252, inbound to France after completing her first war patrol. Her skipper, KL Kai Lerchner, sent a sighting report stating that the convoy was lightly escorted and that he was starting to shadow.

His radio signal was picked up and DFed by Royal Navy land stations and reported to Walker. He quickly dispatched his four corvettes to search for the U-boat, which was picked up on radar by Vetch. As Vetch closed to attack, U-252 crash-dived and launched two torpedoes which narrowly missed the corvette. Arriving in Stork, Walker then sent the others corvettes back to the convoy and commenced a hunt with Vetch Together they made several attacks, dropping 45 depth charges in total, and U-252 was destroyed.
