Lansingerland is a municipality in the western Netherlands, in the province of South Holland.

It was formed on 1 January 2007, by the merger of the municipalities of Berkel en Rodenrijs, Bleiswijk and Bergschenhoek, collectively known as the "B-Triangle".

The name was chosen from a competition and derived from the name Lansingh, the height-of-land between the Delfland and Schieland Water Boards, which runs between the "3B-Triangle" villages.

The choice of name is symbolic: the name of the border that formerly divided the area, now unites it.

The council was renewed in 2022 and sits for four-year cycles in accordance with Dutch municipal election laws.
