The Taça Guanabara (English: Guanabara Cup) is an annual football tournament attached to the Campeonato Carioca, the state football league in the Rio de Janeiro state. It has been organized since 1965 by the Rio de Janeiro State Football Federation. It has had different formats throughout its history.
In its first seven editions (1965, 1966, 1967, 1968, 1969, 1970 and 1971), the Taça Guanabara was a tournament in its own right, unrelated to the Campeonato Carioca, and the winner would represent Rio de Janeiro in the Taça Brasil national league competition. From 1972 onward, the cup became the first round of the Campeonato Carioca. Since 2021, the Taça Guanarabara is the first single round-robin phase of the Campeonato Carioca.
The most successful team in the tournament's history is Flamengo, who have won 25 times.
