Csaba Virag (12 May 1933 - 31 May 2015) was a Hungarian architect. He studied in 1951-1956 at the Budapest University of Technology. In 1957-1962 he continued working at the university, then in 1962 he joined IPARTERV, the state company responsible for industrial architecture. He moved to LAKOTERV, specialized on apartment buildings, in 1972. In 1994 he founded his own office under the name of 'Virag Csaba & Z.H.J. Epitesziroda' with Judit Z. Halmagyi as partner.As a practicioner, Virag has always been open for international influences - he introduced high-tech architecture to Hungary and later opened towards postmodern. His 70s buildings designed in the Buda Castle area show clear and conscious modernity. With his first wife, architect Margit Pazmandi he designed the new headquarters for Hungarian Television and a huge hi-tech center for the Hungarian State News Office - the latter was realized on Buda's Naphegy ter. He produced a wide array of buildings after founding his own office, among the the postmodern Lauder Javne Jewish School and the Kalvin Center office buildings, a controversial glass edifice complex in Budapest's centrally located Kalvin ter. His second wife, Judit Milasovszky, is also an architect. Csaba Virag received the Ybl Miklos Prize in 1968 and 1974.
