Mayfair Games was an American publisher of board, card, and roleplaying games founded in 1981 in Chicago, Illinois. Known for titles like Empire Builder and the Role Aids series, the company gained prominence by introducing Euro-style board games to English-speaking audiences, notably publishing The Settlers of Catan in 1996. Financial difficulties led to its closure in 1997, but it was revived under Ironwind, Inc., continuing to operate under the Mayfair Games trademark.

The company underwent a reorganization in the 2000s, focusing on successful titles like Catan, before transferring its rights to Asmodee’s Catan Studio in 2016. In 2018, Mayfair Games sold its remaining assets to Asmodee North America and shut down. It is remembered for its influential role in bringing popular games like Agricola, 1830, and Patchwork to a broader audience.
