The Chemin de fer de la Matapédia et du Golfe (reporting mark CFMG) (in English, the Matapedia and Gulf Railway) was a short line railway that operated in eastern Quebec from 1998 to 2008.

Owned by the holding company Quebec Railway Corporation (QRC), CFMG operated freight service between Rivière-du-Loup in the west to Matapédia in the east as well as from Mont-Joli to the port of Matane.

The Chemin de fer de la Matapédia et du Golfe was established on 19 January 1998 as a subsidiary of QRC to operate the eastern half of the former Canadian National Railway (CN) Mont Joli Subdivision (this being the former Intercolonial Railway mainline) between Mont-Joli and Matapédia.

At the Port of Matane, CFMG connected with the railcar ferry service to Baie Comeau which was also purchased from CN by QRC and was operated as a separate subsidiary company called Compagnie de gestion de Matane (COGEMA).

This funding was targeted at improving track and bridge infrastructure to allow CFMG to carry heavier freight railway cars.
