'Krumme Lanke' means roughly 'crooked lake'.
The station is named after a long, narrow lake about one kilometre away; it was originally to be called Alsenstraße. A village on the lake, Crumense – a place on a crooked lake – was bought by Lehnin Abbey in 1251. 'Lanke' comes from a Slavic word for water or a bay, used in the region for lakes and bays.
