A texel, or texture element (also texture pixel) is the fundamental unit of texture spaceAndrew Glassner, An Introduction to Ray Tracing, San Francisco: Morgan–Kaufmann, 1989, used in computer graphics. Textures are represented by arrays of texels, just as pictures are represented by arrays of pixels.

When texturing a 3D surface, a process known as texture mapping maps texels to appropriate pixels in the output picture. On modern computers, this operation is accomplished on the graphics card.
