The Museo de Arte Contemporánea de Vigo, also known as MARCO, is an art museum in the city of Vigo, Spain, opened in 2002. The contemporary art museum, which does not have its own permanent collection, is an active arts center and systematically organizes temporary exhibitions of contemporary art.

The building in which it is located dates back to the 19th century and was originally built by the architect José María Ortiz y Sánchez to be a prison. Eventually the palace became a courthouse and a small shelter for the guards. On 6 October 1990, the General Directorate of Heritage of the Galicia Region declared the building a Cultural Heritage. Five years later, in 1995 the cultural project was approved which allowed the building to be rehabilitated and transformed into a contemporary art museum.

The construction of the work was commissioned to a team of architects made up of Salvador Fraga Rivas, Francisco Javier García-Quijada Romero and Manuel Portolés Sanjuán.
