Three Coins in the Fountain is a 1954 American romantic comedy drama film directed by Jean Negulesco from a screenplay by John Patrick, based on the 1952 novel Coins in the Fountain by John H. Secondari. It stars Clifton Webb, Dorothy McGuire, Jean Peters, Louis Jourdan, and Maggie McNamara, with Rossano Brazzi, Howard St. John, Kathryn Givney, and Cathleen Nesbitt. The film follows three American women working in Rome who dream of finding romance in the Eternal City. It was originally titled We Believe in Love.

The film's main title song "Three Coins in the Fountain", sung by an uncredited Frank Sinatra, went on to become an enduring standard. The film was made in Italy during the "Hollywood on the Tiber" era.

At the 27th Academy Awards in 1955, the film received two Academy Awards—for Best Cinematography and Best Song—and was nominated for Best Picture.
