The Espai d'Art Contemporani de Castelló (EACC), in Valencian, is a museum and centre for the production and dissemination of contemporary art located in Castellón de la Plana. It is run by the Instituto Valenciano de Cultura and is one of the leading references for contemporary art in the Valencian Community.

The centre is situated on Calle de Prim, in the heart of the city, behind the Plaza Borrull, next to the Conservatorio de Música and the Escuela Superior de Arte y Diseño.

Its programme includes temporary exhibitions of national and international artists, workshops, performance and "poesía en acción" (poetry in action) meetings, and educational programmes aimed at different audiences. Its activities include collaborations with institutions such as the Museo de Arte Contemporáneo de Castilla y León (MUSAC) and the Colección de Arte Contemporáneo de la Generalitat Valenciana.

The EACC has also promoted cultural mediation initiatives, such as adult schools designed to bring contemporary art closer to non-specialist audiences, and educational programmes that explore artists' creative processes. Its management model combines exhibition with on-site artistic production.
