Donato Raffaele Sbarretti Tazza (November[1] 1856 – 1 April 1939)[2] was an Italian Roman Catholic Cardinal whose career included pastoral service in Italy and Cuba, diplomatic service in America and the Pacific, and ultimately high office in the Roman Curia.

His uncle, Enea Sbarretti, was named a Cardinal in 1877, two years before Donato was ordained a priest at the age of 22.

In 1893, after pastoral work, teaching, and minor curial staff positions, such as a minutante at Propaganda, Sbarretti was made canon of a church in Rome and posted to the United States as auditor in the apostolic delegation.

The United States Government refused to allow him to take up this posting because they wanted to negotiate this issue with their own special mission to the Vatican under William Howard Taft.

He died less than a month after participating in the conclave that elected Pope Pius XII, and according to his will was buried in the parish church of Montefranco, where he had been born.
