Old Leake is one of eighteen parishes which, together with Boston, form the Borough of Boston in the county of Lincolnshire, England. The local government has been arranged in this way since the reorganisation of 1 April 1974, which resulted from the Local Government Act 1972. This parish forms part of the Old Leake and Wrangle electoral ward.
Hitherto, the parish had formed part of Boston Rural District in the Parts of Holland. Holland was one of the three divisions (formally known as parts) of the traditional county of Lincolnshire. Since the Local Government Act of 1888, Holland had been in most respects, a county in itself.
