This category represents the parish of Heydour in the east of the Lincolnshire district  of South Kesteven.  To the north east, the North Kesteven combined parishes of Culverthorpe & Kelby, and Aunsby & Dembleby separates Heydour from the market town of  Sleaford.  To the west, the parish is separated from  Grantham by the B6403 and the parish of  Welby.  In the south, the A52 separates Heydour from the combined parish of Ropsley and Dembleby.

Heydour includes the hamlets of Oasby and Aisby, and until there are separate categories, websites for Welby, Ropsley and Humbsby may be included here.
