The Canal de Montech (French pronunciation: [kanal də mɔ̃tɛʃ]) is an 11 km waterway in southwestern France connecting the Canal de Garonne in Montech and the Tarn River in Montauban.

[1] It is also known as the Montauban Branch (French: l’embranchement de Montauban).

[2] A lock at Moissac also connects the Canal de Garonne to a lower section of the Tarn.

A proposal exists to create a waterway ring, including the Canal de Montech, by restoring navigation to the stretch of the Tarn between Moissac and Montauban.
