Montaner is a frazione in Italy located in the commune of Sarmede, Province of Treviso.

The village is notable for being the location of the Schism of Montaner, following the dispute over the appointment of a local priest.

[2] During the middle ages in Italy, Montaner was the location of the founding of one of the oldest dynasties in the Treviso region, entitled the "da Camino" (Medieval Italian: "da Montanara") before transferring to Oderzo.

The resulting dispute led to the creation of the Orthodox Church of Montaner which was founded under the Byzantine rite, the resulting schism is known as the Schism of Montaner.

[4] The church suffered a fire on 14 December 2013 which made it unusable and subsequently demolished.
