What was Frank Sinatra's full birth name?

Frank Sinatra’s full birth name was Francis Albert Sinatra. He was born on December 12, 1915, in Hoboken, New Jersey, to Italian immigrants Anthony Martin Sinatra and Natalina “Dolly” Garaventa.

Although the world knew him as Frank Sinatra, “Francis Albert Sinatra” is the standard biographical form of his birth name. His first name was often shortened to Frank in everyday life and later became the name under which he built his recording and film career.

There is an unusual complication in the records: his original birth certificate reportedly contained the clerical error “Frank Sinestro.” In May 1945, he officially corrected the record to “Francis A. Sinatra.” That administrative mistake is sometimes mistaken for a genuine alternate birth name, but it does not change the canonical answer used by biographies and reference works.

Sinatra was the only child of his parents. He began performing during the swing era, later becoming known by nicknames including “Ol’ Blue Eyes” and “the Chairman of the Board.” His formal name appears on biographical records even though his stage name became globally famous.
