Joan Antoni Pàmias i Castellà (Barcelona 1903 - 1980) was a Catalan theatre businessman and lawyer. He was the chief of the Great Theatre of Liceu enterprise from 1947 until his death in 1980.

During the time that he was in this position, he fostered the theatre with the creation of an orchestra (1958) and a ballet company (1966). He also enlarged the duration and repertoire of the ballet and opera seasons. He hired first-rate soloist and companies. He published several articles about music matters. In 1955 he arranged for the Bayreuth festival to visit Barcelona. In 1959 he received the Spanish Premio Nacional de Teatro (National Theatre Prize).
