Tom Clancy's SSN is a 1996 submarine simulator of the 688i (Improved Los Angeles-class nuclear hunter/killer submarine) released on Microsoft Windows. The player is in command of USS Cheyenne in a limited war against China over the Spratly Islands. The gameplay is limited to a 15-mission single-player campaign in which the player carries out anti-submarine, anti-surface ship roles, intelligence gathering activities, and the launch of submarine based cruise missiles. Tom Clancy also wrote a book by the same name as a tie-in.

SSN is also the title of a board wargame published by Game Designer's Workshop in 1975, and was the first attempt at a serious modern submarine and anti-submarine warfare simulation game published for the entertainment market. It was designed by Stephen Newberg and developed by Marc Miller.
