Buona Sera, Mrs. Campbell is a 1968 American comedy film starring Gina Lollobrigida, Shelley Winters, Phil Silvers, Peter Lawford and Telly Savalas. It was produced and directed by Melvin Frank, who co-wrote the original screenplay with Denis Norden and Sheldon Keller.

The United Artists release was filmed at Cinecitta Studios, Rome. It served as the basis for the unsuccessful 1979 stage musical Carmelina. Some critics have also speculated that the 1999 stage musical Mamma Mia!—and, by extension, its 2008 film adaptation—are based on Buona Sera, Mrs. Campbell, although the musical's book writer, Catherine Johnson, has denied any connection.
