Battle for Terra, originally screened as Terra, is a 2007 American animated action-adventure science fiction film, based on the short film Terra, about a race of beings on a peaceful alien planet who face destruction from colonization by the displaced remainder of the human race. The film was directed by Aristomenis Tsirbas who conceived it as a hard-edged live action feature with photo-real Computer-Generated Imagery (CGI) environments. The close collaboration with producing partner and investor Snoot Entertainment redirected the project to become fully animated and appeal to younger audiences. The film features the voices of Evan Rachel Wood, Luke Wilson, Brian Cox and James Garner (In his last major film role before his death) among others.

It premiered on September 8, 2007 at the Toronto International Film Festival and was widely released in the United States on May 1, 2009 by Lionsgate and Roadside Attractions.

The film was originally shot in 2D but was made in such a way that a second camera could be added to the film. After the film was shown at festivals and distributors showed an interest in it, a small team was hired to render the entire film again from the perspective of the second camera for a true 3D effect. It won the Grand Prize for Best Animated Feature at the 2008 Ottawa International Animation Festival.
