Robert Benedetto (born October 22, 1946, in The Bronx, New York) is an American luthier of archtop jazz guitars.

By the 1970s (he relocated to Florida in 1976), his reputation grew as he crafted archtop guitars for professional jazz players Bucky Pizzarelli, Chuck Wayne, Joe Diorio and Cal Collins, and in the 80s and 90s for Johnny Smith, Jack Wilkins, Ron Eschete, Martin Taylor, Howard Alden, John Pizzarelli, Andy Summers, Jimmy Bruno, Kenny Burrell and Pat Martino, among others, collectively known as “The Benedetto Players”.

More recent jazz guitarists who play Benedetto guitars include Dan Faehnle, Joe Negri, Chico Pinheiro and Andreas Varady.

Benedetto married Cindy Whyte in 1975 who has photographed and extensively documented Robert’s guitars and their players.

In 2018, a Benedetto 50th Anniversary concert was presented by the Savannah Music Festival featuring Howard Alden, Chico Pinheiro, Romero Lubambo, "King" Solomon Hicks and Pat Martino.
