Clatworthy Camp is an Iron Age hill fort 3 miles (4.8 km) North West of Wiveliscombe, Somerset, England. It has been scheduled as an Ancient Monument. Due to the vulnerability to scrub and tree growth it has been added to the Heritage at Risk Register.

The history of the site is unclear but appears to have been used between the Bronze and Iron Ages. It is situated on a promontory of the Brendon Hills above Clatworthy Reservoir. It is roughly triangular in shape with an area of 5.8 hectares (14 acres). It has a single bank and ditch, cut through solid rock. There may have been an entrance on the west and two on the east. The interior has postholes from timber or stone houses and some storage pits.

In 2014 and 2015 Wessex Water undertook tree clearance and the removal of bracken from the site without disturbing badger setts and potential bat roosts. Information boards about the local wildlife were also installed.

Hill forts developed in the Late Bronze and Early Iron Age, roughly the start of the first millennium BC. The reason for their emergence in Britain, and their purpose, has been a subject of debate. It has been argued that they could have been military sites constructed in response to invasion from continental Europe, sites built by invaders, or a military reaction to social tensions caused by an increasing population and consequent pressure on agriculture. The dominant view since the 1960s has been that the increasing use of iron led to social changes in Britain. Deposits of iron ore were located in different places to the tin and copper ore necessary to make bronze, and as a result trading patterns shifted and the old elites lost their economic and social status. Power passed into the hands of a new group of people. Archaeologist Barry Cunliffe believes that population increase still played a role and has stated "[the forts] provided defensive possibilities for the community at those times when the stress [of an increasing population] burst out into open warfare. But I wouldn't see them as having been built because there was a state of war. They would be functional as defensive strongholds when there were tensions and undoubtedly some of them were attacked and destroyed, but this was not the only, or even the most significant, factor in their construction".
