Bourne was a rural district in Lincolnshire, Parts of Kesteven from 1894 to 1931.
It was created by the Local Government Act 1894 based on the Bourne rural sanitary district. In 1931, under a County Review Order, it was abolished, with its area going to form part of the new South Kesteven Rural District.
