Otto Adalbert Schnee (31 December 1913 – 4 November 1982) was a Korvettenkapitän (corvette captain) with Nazi Germany's Kriegsmarine during World War II.

He spent two years on board the Type IIB U-boat U-23, under the command of Oberleutnant zur See Otto Kretschmer, completing five combat patrols as 1.WO (second-in-command), between October 1939 and January 1940.

[1] Schnee's first command, from January to July 1940, was the Type IIA submarine U-6,[1] in which he sailed on only a single short patrol in April supporting "Operation Weserübung" (the invasion of Norway).

The next day Schnee received the cease-fire order, prior to the German surrender, and a few hours later spotted a group of British warships.

Simulating an attack, he evaded the destroyer screen, closed to within 500 metres (1,600 ft) of the British cruiser Norfolk, and then left the area without being detected.

In October 1945 he was called to testify at the trial of Heinz-Wilhelm Eck and the officers of U-852, for their actions after the sinking of SS Peleus.
