Gallium3D is a free software library for 3D graphics device drivers. It has been developed by VMware since they acquired Tungsten Graphics in 2008.

The Gallium3D library operates as a layer between the graphics API and the operating system with the primary goal of making driver development easier, bundling otherwise duplicated code of several different drivers at a single point, and to support modern hardware architectures. This is done by providing a better division of labor, for example, leaving memory management to the kernel DRI driver.

Gallium3D has been a part of Mesa since 2009 and is currently used by the free and open source graphics driver for Nvidia (nouveau project),and by the free and open source graphics driver for ATI Radeon R300-R900.
