The Welsh Chess Union ({{langx|cy|Undeb Gwyddbwyll Cymru}}) is the national chess federation for Wales. Formed on 19 June 1954 as a Union of Associations in South Wales and Monmouthshire, it was originally a part of the British Chess Federation (BCF). The Union established the Welsh Championship in 1955. On 15 November 1969 it withdrew from the BCF to apply for membership in the World Chess Federation (FIDE) as an independent body. FIDE accepted the application at the Siegen Congress in 1970 and Wales competed in its first Olympiad at Skopje 1972, finishing 43rd of 62.

Its objects are to promote, organise and regulate the playing of competitive chess throughout Wales. Its moto is "Ymosodiad Dewr; Amddiffyniad Sicr" - "Bold in Attack; In Defence Secure".
