Beach Chair is a 30-second American short computer animation test clip created by animator Eben Ostby for Pixar in 1986. It depicts a chair walking across the sand, dipping its leg into the water, and then moving along. Ostby made the project with the feedback of John Lasseter to work out details of rendering software.

It was exhibited at SIGGRAPH in Dallas in 1986, along with Lasseter’s landmark computer-animated short Luxo Jr. and another test project, Flags and Waves by Bill Reeves. Beach Chair can also be found as an Easter egg in Pixar Short Films Collection – Volume 1, which was released in 2007.

In 1991, it was shown on an episode of MTV's Liquid Television.

The test was lasting just 30 seconds and it contain sound effects on.
