The municipality of Laanke was created on 1 January 1902 when the old municipality of Nedre Stjørdal was split into three new municipalities: Laanke, Stjørdal, and Skatval. Initially, Laanke had a population of 1,449. On 1 January 1914 a small part of Laanke with 38 inhabitants was transferred to Malvik in neighboring Sør-Trøndelag county. The spelling was later changed to Lånke. On 1 January 1962, Lånke was merged with the neighbouring municipalities of Stjørdal, Hegra, and Skatval to form a new, larger municipality of Stjørdal. Prior to the merger, Lånke had a population of 1,967.
