Dunham Castle is an early medieval castle in Dunham Massey, Greater Manchester, England (grid reference SJ73428742).

Documentary evidence suggests the castle at Dunham was still standing in 1323.

It probably existed on a mound, or motte, near the site of where Dunham Massey Hall is today.

[1] The site was surrounded by a moat which was later turned into an ornamental lake.

[2] Dunham Castle was a Scheduled Ancient Monument, but was delisted.
