The Funiculaire de Cossonay is a funicular railway connecting the town of Cossonay in the Swiss canton of Vaud with Cossonay-Penthalaz railway station, on the line from Lausanne to Vallorbe and Yverdon-les-Bains. The lower funicular station is called Cossonay-Gare, but is in the village of Penthalaz. The upper station, some 130 metres (430 ft) above, is named Cossonay-Ville . The line has a length of 1228 m at a maximum incline of 13%.

The line was opened in 1897, and was initially operated as a water counterbalance funicular. In 1969, the line was automated, still as a water counterbalance funicular. In 1982, the line was rebuilt and converted to electric operation, with new cabins and stations.

The funicular was again completely overhauled between 2012 and 2014, reopening on June 10. At the same time, the 1982-built cabins were refurbished and repainted in its owner's green and cream. During the overhaul period, a replacement bus operated the connection.

The Compagnie du Chemin de fer Funiculaire de la Gare à la Ville de Cossonay , after a name change in 2003 Funiculaire de la Gare à la Ville de Cossonay SA, was founded in 1892. In 2010 the company was merged into the Transports de la région Morges-Bière-Cossonay, which had assumed operation already before, but then on behalf of the original owner company.
