Operation Obviate was an unsuccessful British air raid of World War II which targeted the German battleship Tirpitz. It was conducted by Royal Air Force heavy bombers on 29 October 1944, and sought to destroy the damaged battleship after she moved to a new anchorage near Tromsø in northern Norway.

Tirpitz was the second of two Bismarck-class battleships built for Nazi Germany's Kriegsmarine (navy) prior to and during the Second World War. Named after Grand Admiral Alfred von Tirpitz, the architect of the Kaiserliche Marine, the ship was laid down at the Kriegsmarinewerft in Wilhelmshaven in November 1936 and her hull was launched two and a half years later. Work was completed in February 1941, when she was commissioned into the German fleet. Like her sister ship, Bismarck, Tirpitz was armed with a main battery of eight 38-centimetre (15 in) guns in four twin turrets. After a series of wartime modifications she was 2000 tonnes heavier than Bismarck, making her the heaviest battleship ever built by a European navy.
