Maiden Bower is an Iron Age hillfort near Dunstable in Bedfordshire, England.

[1] The fort is situated on a plateau, and there is a disused chalk quarry on the north-western side.

It is roughly circular, about 225 metres (738 ft) in diameter, enclosing an area of about 4.9 hectares (12 acres).

Across the entrance was found a large pit with the disarticulated remains of about 50 persons, thought to be a ritual mass reburial rather than an indication of warfare.

Worthington Smith in 1907 discovered a small early Roman cremation cemetery on the north-west side of the fort where the quarry was encroaching; Samian ware and other pottery of the period was found.
