Super Robot Wars OG (スーパーロボット大戦OG オリジナルジェネレーションズ, Sūpā Robotto Taisen Ōjī Orijinaru Jenerēshonzu) is a 2007 tactical role-playing game for the PlayStation 2.

OG is developed by the team that produced Super Robot Wars MX and uses high-energy, dynamic action for the in-game battle sequences.

A small, but significant change in gameplay are the Spirit Commands, character abilities akin to magic spells.

This makes Original Generations the first game in the franchise to break the six Spirit Command limit.

The game's soundtrack was released in Japan by Lantis on September 5, 2007, with a retail price of 3,619 Yen.
