Versus (ヴァーサス, Vāsasu) is a 2000 Japanese zombie action horror film directed and co-written by Ryuhei Kitamura. The film was an independent co–production between Kitamura's company Napalm Films and Wevco Production in association with KSS and Suplex. In the film, a nameless prisoner, a nameless female and her Yakuza abductors fend off zombies in a forest that resurrects the dead while the Yakuza's mysterious leader attempts to open a supernatural gate hidden within the forest and seize its dark power.

The film was originally intended as a sequel to Kitamura's short film Down to Hell but was re-developed as a new film. Principal photography was originally intended to last 3 weeks but was extended to 7 months due to weather and financial issues.

Versus premiered at the Tokyo International Fantastic Film Festival on October 29, 2000. In 2004, an expanded edition titled Ultimate Versus was released that featured 10 minutes of new footage and improved music, effects, titles, and edits.
