Robert Tatton (1606 – 19 August 1669) was a Cheshire landowner who supported King Charles I in the Civil War.

He inherited the family estate in Wythenshawe, then in Cheshire, aged ten, and married Anne Brereton in 1628. When Civil War broke out, he joined the Royalist side, despite his wife being closely related to Sir William Brereton, who commanded the Parliamentary forces in Cheshire. Tatton is perhaps best known for his defence of his family home, Wythenshawe Hall, during its three-month siege in the winter of 1643/44 by a Parliamentary force commanded by Robert Duckenfield. Parliamentary casualties included Duckinfield's second-in-command, but their victory was inevitable when cannons were brought in. On surrender, the hall's contents were valued at almost £1650 (now around £230,000).

Tatton served as the High Sheriff of Chester between 1645 and 1646. Although heavily fined by Parliament for fighting on the side of the king, he was subsequently rewarded for his loyalty by Charles II following the restoration of the monarchy in 1660. The Wythenshawe estate remained in the Tatton family until the 1920s.
