Chûn Castle is a large Iron Age hillfort (ringfort) near Penzance in Cornwall, England, United Kingdom. The fort was built about 2,500 years ago, and fell into disuse until the early centuries AD when it was possibly re-occupied to protect the nearby tin mines. It stands beside a prehistoric trackway that was formerly known as the Old St Ives Road and the Tinners’ Way. The name Chûn derives from Cornish: Chi an Woon (‘the house on the downs’). The area is now sometimes known as Chûn Downs.

Edward Lluyd made a plan of this fort in around 1700, remarking that its structure and security showed, "military knowledge superior to that of any other works of this kind which I have seen in Cornwall". What is of note is the fact that the fort has a strategic inner and outer wall and ditch. The remains today are still clearly visible despite the fact that the once twenty-feet-odd walls now stand at around five feet due to its use in the 19th century as a quarry for buildings in Penzance and Madron.

The fort was excavated in 1895, 1925, 1927 and 1930. Much pottery was uncovered, the earliest dating to the 4th century BC due to its similarity to known Breton pottery of that age. However, it is possible that the fort was built upon a much older structure. Chûn Quoit, around 800 feet to the west, is dated to around 2400BC.

The purpose of the fort is speculated to be for protection of tin and copper gathered in the tin-rich locality of what is now Pendeen, with its Geevor Tin Mine, and surrounding villages. Iron and tin slags were found within the castle, near the well. It overlooks many miles of ocean, the Celtic Sea, to the north, and overlooks the only land route to this peninsula (West Penwith) to the south. Therefore, not only its structure but its location suggest a much more actively militaristic function.
