Breidden Hill is a steep-sided prominence reaching 367 m near Welshpool in Powys, Wales. Its summit holds a large Iron Age hillfort occupied through the Bronze and Iron Ages into the Roman period, with remains of a defensive ditch, stone inner bank, and outer bank still visible. Excavations revealed timber roundhouses and other structures within the fort. The site has been traditionally linked to the last stand of Caractacus against the Romans, though this identification remains debated.
