Tomb Raider II: Golden Mask (North American title: Tomb Raider II Gold) is an expanded version of Tomb Raider II released in 1999 for Windows and Macintosh. The game comprises the scenarios of the original game with the addition of five new bonus levels in a separate mini-adventure entitled the "Golden Mask". Unlike the other two expanded games however, this contains no story ties to its corresponding game from the main Tomb Raider series. Its plot is completely unique.

The story involves Lara Croft coming across some clues referring to a small island in the Bering Sea: a faded photograph showing an Inuit whale hunter holding what looks like an ancient Golden Mask, an old newspaper from 1945 referring to a conflict over an Alaskan gold discovery, and a secret kind of fortified military mine base. Lara is primarily interested in finding the Mask, as it is rumoured to be the famed Golden Mask of Tornarsuk - a greater spirit said to bestow powers of re-animation on the mask wearer.
