A checkerboard is a board on which checkers is played. It is an 8×8 board and the 64 squares are of alternating color; usually, but not necessarily, black and white. The game of chess is played on a similar board.

The term checkerboard is also used to denote any rectangular square-tiled board. In this sense it refers not to a physical board as such but to the mathematical abstraction of such a board. The adjective checkered may refer to a pattern resembling a checkerboard, as in the checkered flag used to welcome the winning cars in a Formula One race, for instance.
