The Chemins de fer départementaux du Finistère were a metre gauge railway system in northwest Brittany, France. It was opened in stages between 1893 and 1907, and closed in 1946. The system had a total extent of 214 kilometres (133 mi).

In France, a voie ferrée d'intérêt local, abbreviated VFIL, is a secondary railway constructed by a local administrative division, serving sparsely populated rural areas. These areas were beyond the economic reach of the networks of the intérêt général, which were concessions of the grandes compagnies who ran their lines for profit.
