Fontana del Tritone is a seventeenth-century fountain in Rome, by the Baroque sculptor Gian Lorenzo Bernini. Commissioned by his patron, Pope Urban VIII, the fountain is located in the Piazza Barberini, near the entrance to the Palazzo Barberini that Bernini helped to design and construct for the Barberini, Urban's family. This fountain should be distinguished from the nearby Fontana dei Tritoni by Carlo Francesco Bizzaccheri in Piazza Bocca della Verità which features two Tritons.

Gian Lorenzo Bernini was an Italian sculptor and architect. While a major figure in the world of architecture, he was more prominently the leading sculptor of his age, credited with creating the Baroque style of sculpture.
