Ring of Red is an alternate history turn-based strategy video game released by Konami for the PlayStation 2 console. It was one of the first PlayStation 2 games made with CD-ROM-based technology. Ring of Red was released in 2000 for Japan followed by North America and Europe in 2001. An emulated version for the PlayStation 3 was released as a PS2 Classic on October 4, 2011 in North America.

The game is based on an alternate history theory that after the defeat of Nazi Germany and Fascist Italy near the end of World War II, Japan was conquered and occupied by both Soviet and American forces - rather than solely by the US, as in actual history. The occupation created two countries, consisting of the north governed by a pro-communist government and the south by a pro-democracy government with Hokkaidō occupied by Soviet forces. Tensions between the two Japans were at an all-time high during the Cold War with a Japanese War (similar in cause to the actual Korean War) taking place with Armored Fighting Walkers, giant walking mechas being used with great success by both the North and South Japanese militaries.
