Loki Software, Inc. was an American video game developer based in Tustin, California, that ported several video games from Microsoft Windows to Linux. It took its name from the Norse deity Loki. Although successful in its goal of bringing games to the Linux platform, the company folded in January 2002 after filing for bankruptcy.

Civilization: Call to Power is a turn-based strategy game developed by Activision for Microsoft Windows as an attempt to capitalize on the success of the Civilization computer games by Sid Meier. It was ported to Linux by Loki Software, as well as BeOS by Wildcard Design, becoming one of the very few commercial games for that operating system.
