Pietro Baratta (1659–1729) (17th century) was an Italian sculptor of the Baroque period, active in Venice.
Born in Carrara, Tuscany, he worked in Venice and Udine, at the villas on the mainland and as a landscape architect.
He was the nephew of the sculptor Francesco Baratta the elder (1590–1666), who had worked in Rome in the studio of Bernini.
He is responsible for the sculptures in the facade of the Villa Manin's Chapel at Passariano di Codroipo (Udine); these include the statues of the four Evangelists and of the Madonna with the Child.
Pietro Baratta is the author of the statue of St Ignatius of Loyola, shown in a contemplative attitude, with an open Bible in his hands, for the church of Santa Maria Assunta (I Gesuiti) in Venice.
