Aubourn Haddington and South Hykeham

Aubourn Haddington and South Hykeham is a former civil parish in the North Kesteven district of Lincolnshire, England. According to the 2001 census it had a population of 885.

The parish included the villages of Aubourn, Haddington and South Hykeham. The A46 (the old Fosse Way) formed the north-western border of the parish.

The composite parish was formed on 1 April 1931 from the separate parishes of Aubourn, Haddington, and South Hykeham in 1991 and order was made to dissolve the parish to become two separate parishes: Aubourn and Haddington and South Hykeham. However the order was deficient for failing to define a new boundary between South Hykeham and "Aubourn with Haddington". On 1 March 2011 the parish was abolished and split which implemented the 1990 order that was to come into effect in 1991.
