A fairy chess piece is a game piece that is not in regular chess but appears in an alternate version of chess with different rules. Such an alternate version is known as a chess variant. In addition, fairy chess pieces are used in fairy chess, an area of chess problems involving changes to the rules of chess.

The following table shows some game pieces of unorthodox chess, from fairy chess problems and chess variants (including historical and regional ones), and the six orthodox chess pieces. The columns "BCPS", "Parlett" and "Betza" contain the notation describing how each piece moves. The notation systems are explained in this page.
