HMS Venturer was a Second World War British submarine of the V class that sank two German U-boats and five merchant ships during the war. Following the war, the boat was sold to Norway and was renamed HNoMS Utstein. She was discarded in 1964.

She is the only submarine in history to have sunk another while both were submerged.
