Birdemic: Shock and Terror is a 2010 American independent romantic thriller-horror film written, directed, and executive produced by James Nguyen, and starring Alan Bagh and Whitney Moore. Inspired by Alfred Hitchcock's The Birds, Birdemic tells the story of a romance between the two main characters as their small town is attacked by birds. It also was inspired by the environmental documentary An Inconvenient Truth, which led to the film having an environmental message.

The film was largely self-financed and was produced through Nguyen's Moviehead Pictures company for a budget of $10,000. The film has gained notoriety for its poor quality, with many critics citing it as one of the worst films of all time. After a limited theatrical release, the film was picked up for distribution by Severin Films in 2010. A sequel, Birdemic 2: The Resurrection, was released in 2013. A second sequel, Birdemic 3: Sea Eagle, was released in 2022.
