Low Dinsdale Manor is a privately owned, much altered, and extended medieval moated fortified manor house situated on the north bank of the River Tees at Low Dinsdale, near Darlington, County Durham, England.

Several members of the Surtees of Dinsdale family served as High Sheriff of Northumberland.

In 1511 on the death of the last male of the family it passed to his daughter Katherine Place.

In 1844 the Earl sold the manor to Henry George Surtees (High Sheriff of Durham 1862) a descendant of the ancient family.

He substantially extended and altered the house in 1876 adding new bays to the medieval core and two cross-gabled wings.
