Bonaventura Cerretti (17 June 1872 – 8 May 1933) was an Italian cardinal of the Roman Catholic Church.

He served as Prefect of the Supreme Tribunal of the Apostolic Signatura from 1931 until his death, and was elevated to the cardinalate in 1925.

In 1925 he was made Cardinal-Priest of Santa Cecilia in Trastevere by Pope Pius XI in the consistory of 14 December 1925.

In 1928 he revisited Australia as papal legate to the 29th International Eucharistic Congress in Sydney; as part of this visit, he laid the foundation stone for the Holy Name Cathedral, Brisbane (which was never completed).

Monsignor Caesar Cerretti (died February 1936), Canon of St. Peter's, Rome, was a brother.
