Letcombe Regis is a village and civil parish in the Vale of White Horse.
The village is on Letcombe Brook at the foot of the Berkshire Downs escarpment about 1 mile (1.6 km) southwest of the market town of Wantage.

The centre was initially a UK government laboratory, but was sold to the chemical company Dow Elanco in 1985.
