Castle Wolfenstein is a 1981 action-adventure game developed by Silas Warner for the Apple II and published by Muse Software in 1981. It is one of the earliest games based on stealth mechanics. A port to Atari 8-bit computers was released in 1982, followed by Commodore 64 (1983) and MS-DOS (1984).

The game takes place during World War II. The player takes the role of an Allied prisoner of war who is held captive in the fictional Castle Wolfenstein. After escaping from the cell, the player's objective is to find the Nazis' secret war plans and escape from the castle. Nazi soldier enemies can be dealt with by impersonating, sneaking, or killing them.

The game was received positively amongst critics and became one of the best-selling games of the early 1980s. It is considered to have had a direct influence on modern stealth games. The game was praised for its graphics, and gameplay, but criticized for its long waiting times when opening chests.
