The Graphophone was the name and trademark of an improved version of the phonograph. It was initially designed at the Volta Laboratory established by Alexander Graham Bell in Washington, D.C., United States. It was co-invented by Alexander Graham Bell, Charles Sumner Tainter, and Chichester Bell in 1886.

Its trademark usage was acquired successively by the Volta Graphophone Company, the American Graphophone Company, the North American Phonograph Company, and finally by the Columbia Phonograh Company (known today as Columbia Records), all of which either produced or sold Graphophones.
