Ehrgeiz, fully titled Ehrgeiz: God Bless the Ring, is a 1998 fighting game developed by DreamFactory and published by Namco for arcades. It was developed as a partnership between Square and DreamFactory. It was ported to the PlayStation, where Square released it internationally while Sony Computer Entertainment published it in Japan, a direct inversion of the companies' usual publishing deal.

The game includes characters from Final Fantasy VII: Cloud Strife, Tifa Lockhart – which are playable in both versions; Sephiroth, Yuffie Kisaragi, Vincent Valentine, and Zack Fair – which were added to the PlayStation's roster exclusively.
