Montricoux (French pronunciation: [mɔ̃ʁiku]; Occitan: Montricós) is a commune in the Tarn-et-Garonne department in the Occitanie region in southern France.

On the right bank of the Aveyron, Montricoux, with an area of 2644 hectares, lies in lower Quercy where the river leaves the limestone gorges of the Massif Central for the plain.

Flints from northwestern France and the ]Périgord have been found in Montricoux and a number of other sites in the Aveyron valley, providing evidence for the travel of ancient nomads through the region.

[5] It was still known as Mormac in 767 when King Pepin the Short, honoring a vow made before his victory over Waiofar the Duke of Aquitaine, donated the land and the monastery of Saint Antonin to the monks who lived there.

[12] Article 13 of the city charter of January 6, 1277 forbade the townspeople from fishing in their pond, which has since disappeared as the river receded.

[3] Like those at Nègrepelisse, Caussade, and the Basilica of Saint Sernin,[5] it is of "Toulouse style",[23] an octagonal brick tower with miter windows on a square stone socle, flanked by a turret.

[22] Today the streets of Montricoux offer many fine examples of timber framing,[3] many of them dating from a period of rebuilding after the Hundred Years’ War.

[24] Members of the maquis, the decentralized French Resistance movement in World War II, were captured in Montricoux and hanged on July 23, 1944 by German soldiers.
