The Women's World Chess Championship was held from 16 March to 7 April 2015 in Sochi, Russia. It was a 64-player knockout tournament. It was originally scheduled from 11 to 31 October 2014 but problems in finding a sponsor and host city eventually forced international chess organisation FIDE to announce the postponement of the Championship on 24 September 2014, scheduling it for early 2015 in Sochi. The unclear state of the tournament was highly criticised by the Association of Chess Professionals (ACP).

The Women's World Chess Championship is a chess match played to determine the Women's World Chess Champion. It has been administered by FIDE since its inception in 1927, unlike the absolute World Chess Championship, which only came under FIDE's control in 1948.
