The Compagnie des chemins de fer de Paris à Lyon et à la Méditerranée (also known as PLM) was a French railway company that was created between 1858 and 1862 from the amalgamation of the earlier Paris-Lyon and Lyon-Méditerranée companies. The PLM operated chiefly in the south-east of France, with a main line which connected Paris to the Côte d'Azur by way of Dijon, Lyon, and Marseille. The company was also the operator of railways in Algeria. It was absorbed into the majority state-owned Société Nationale des Chemins de fer Français, in 1938, with the PLM's network becoming the south-eastern region of SNCF.
