A/S Lollandsbanen was a Danish railway company operating the Nykøbing F–Nakskov line mostly on the island of Lolland. Established in 1954, it was based on the remains of Det Lolland-Falsterske Jernbane-Selskab (LFJS). The company received funding from the now defunct Storstrøm County and from the central government.
The company was merged with Vestsjællands Lokalbaner A/S and Østbanen into a new company, Regionstog A/S, on 1 January 2009.
