The United States Access Board (also known as the Architectural and Transportation Barriers Compliance Board) is an independent agency of the United States government devoted to accessibility for people with disabilities. The Board was created in 1973 to ensure access to federally funded facilities. It develops and maintains design criteria for the built environment, transit vehicles, telecommunications equipment, and electronic and information technology. It also provides technical assistance and training on these requirements and on accessible design and continues to enforce accessibility standards that cover federally funded facilities.

The Board is structured to function as a coordinating body among federal agencies and to directly represent the public, particularly people with disabilities. Half of its members are representatives from most of the federal departments. The other half are members of the public appointed by the U.S. President, a majority of whom must have a disability.
