Orvosegyetem Sport Club is a Hungarian professional water polo club from Budapest established in 1957 in the Semmelweis University.

The club's peak was the 1970s. Orvosegyetem won six national championships in a row between 1969 and 1974, and in 1973 it won the European Cup, beating 4-times champion Partizan Belgrade in the final. In 1974 and 1975 also reached the European Cup's final, but lost to MGU Moscow and Partizan respectively. In 1976 it played its fourth European final, losing the Cup Winners' Cup to Mladost Zagreb. In 1978 and 1979 the team culminated its golden era winning its seventh national championship and its second European Cup. The team declined in subsequent years, but it still played in the Hungarian First Championship.

However, with the team moving to XI. district in Budapest, and with the new title sponsor, A-HÍD Zrt. from the 2014–15 season was a very successful one, winning silver medal in both the Hungarian Cup and the Hungarian Championship, whilst also going three rounds in the LEN Champions League qualifiers before falling out against Szolnoki VSC.
