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

Ten years before Montauban a count's castle was built nearby, around which a new town developed.

The city became royal in 1271, at the time of Philip III the Bold who granted it a charter of which several old copies, in Latin, exist.

Originally, the parish church of Saint Etienne and its cemetery were located to the northeast of the town, a few hundred meters away.

The French Wars of Religion made Montech a bastion of Catholicism against Protestant Montauban.
