Red Orchestra: Ostfront 41–45 is a 2006 multiplayer tactical first-person shooter video game based on its predecessor Red Orchestra: Combined Arms. After winning the Make Something Unreal contest, the team behind the original Red Orchestra started the game studio Tripwire Interactive and developed Red Orchestra: Ostfront 41–45 as their first project.

Set on the Eastern Front during World War II between 1941 and 1945, Red Orchestra: Ostfront 41–45 depicts the struggle between Soviet and German forces. The game's creators, Tripwire Interactive, developed the game out of the previous Unreal Tournament 2004 mod, Red Orchestra: Combined Arms.

As of April 2009, the game has sold around 400,000 copies.
