The Oratory of San Nicola da Tolentino (in Italian, Oratorio di San Nicola da Tolentino) is a small chapel like structure in Vicenza, which is notable for its excellent collection of 16th- and 17th-century paintings.
Built starting in 1505 for the Venerable confraternity of the saint, construction was completed by 1681, when the facade was finished (attributed to Carlo Bottiron). It is dedicated to Saint Nicholas of Tolentino.
The interior has a number of canvases based upon events and miracles in the life of San Nicola, many inserted in niches in the wall.

Three statues inside were completed in 1679 by Francesco Pozzo, including a "Madonna and child", "St. Augustine", and "St. Nicola". Giuseppe Alabardi also has a work here.
