West Coker is a large village and civil parish in Somerset, England, situated 3 miles (4.8 km) south west of Yeovil in the South Somerset district.
The name Coker comes from Coker Water (crooked stream from the Celtic Kukro).
Artifacts from early settlement in the parish include a polished stone axe and boat shaped-bronze broach. A Roman villa has been excavated and a bronze plate inscribed to the god Mars discovered. From this Mars was given the title Mars Rigisamus (which means 'Greatest King' or 'King of Kings') as it depicts a standing naked male figure with a close-fitting helmet; his right hand may have once held a weapon, and he probably originally also had a shield (both are now lost). The same epithet for a god is recorded from Bourges in Gaul. The use of this epithet implies that Mars had an extremely high status, over and above his warrior function.
The manor descended with its neighbour East Coker until the 14th century when it passed to a junior branch of the Courtenay family. It was later held by the Dukes of Somerset and Northumberland protectors of Edward VI and later still by the Portmans of Orchard Portman.
