The Taça Guanabara, or Guanabara Cup, is a football tournament organized annually since 1965 by the Rio de Janeiro State Football Federation. In its first four editions (1965, 1966, 1967 and 1968), the Taça Guanabara was a tournament in its own right, unrelated to the Rio de Janeiro league, and the winner would represent Rio de Janeiro in the Taça Brasil de Futebol national league competition. From 1969 onward, the cup became the first round of the Rio de Janeiro state league.
