The Chemin de fer de la Rivière Romaine (reporting mark CFRR) (French pronunciation: [ʃəmɛ̃ də fɛʁ də la ʁivjɛʁ ʁɔmɛn]; in English, the Romaine River Railway) is a Canadian short line iron ore mining railway operating in eastern Quebec.

The railway runs for 43 km (27 mi) from the port of Havre-Saint-Pierre on the north shore of the Saint Lawrence River inland to a massive ilmenite (titanium iron) deposit at Lac Allard.

At Havre-Saint-Pierre, the mineral is loaded aboard bulk carriers and shipped upriver to the port of Sorel-Tracy.

[1] QIT also operates passenger trains for workers, as the mine is not accessible by road.

[2] The Romaine River Railway began operating in 1949 and is owned and operated by QIT-Fer et Titane, which is a subdivision of the Anglo-Australian company Rio Tinto Group.
