Eslington Park is a privately owned 18th-century mansion house west of Whittingham, Northumberland, near the River Aln.

[1] Eslington, first mentioned in the reign of Edward III in 1335, was held in early times by a family who took that name.

It later passed into the hands of the Hazelriggs, the Herons, and then the Collingwood's, who lost all when George, the head of the family, was executed for treason in 1716.

The Liddells purchased the Eslington estates from the Crown, and the head of the family, Lord Ravensworth, became the chief landowner.

A survey of 1541 reported that the house, in the ownership of Hesilrige but occupied by Robert Collingwood, was in 'good reparation'.
