Santi Pietro e Tommaso is the Roman Catholic parish church in town of Montasola, in the province of Rieti, region of Lazio, Italy.
The church at the site was first commissioned in 1191 by Pope Celestine III, and was dependent on the Abbey of Farfa.
The rose marble balustrade was installed in 1923, and derives from the former church of Santa Maria Murella.
The second altarpiece on the left has an altar dedicated to St Prospero, derived from the former church of San Antonino.
The framed cassettes in the ceiling date to the 16th-century and include a canvas derived also from Santa Maria Murella, depicting the Virgin and Child with Saints Peter and Charles Borromeo and a donor.
