'Lambeth' means the landing place for lambs.
It was first recorded in 1062 as Lambehitha, from Old English lamb and hythe, a landing place, as in Rotherhithe: a harbour from or to which lambs were shipped. The station opened in 1906 as Kennington Road, became Westminster Bridge Road that July, Lambeth (North) in 1917 and Lambeth North in 1928.
