Maxey Castle was a medieval fortified manor house castle in Maxey, Cambridgeshire, England.

Maxey Castle was built around the 1370s by William Thorpe near the village of Maxey.

[1] The castle had a double moat, possibly designed as a flood defence, with a central keep within a bailey wall with corner towers.

[1] Margaret Beaufort, Countess of Richmond and of Derby, and mother of King Henry VII lived here in the 15th century.

[dubious – discuss] Only the partial remains of the moats survive of the castle, which have scheduled monument status.
