Wantage was a rural district of Berkshire, England from 1894 to 1974.
It was created in 1894 as a successor to the Wantage rural sanitary district. It was named after Wantage, which formed a separate urban district entirely surrounded by the rural district. It had its headquarters in Belmont, Wantage.
The district was abolished in 1974 (as were all other rural districts, under the Local Government Act 1972). Its area was split, with the parishes of Ardington, Blewbury, Childrey, Chilton, Denchworth, East Challow, East Hanney, East Hendred, Goosey, Grove, Harwell, Letcombe Bassett, Letcombe Regis, Lockinge, Sparsholt, Upton, West Challow, West Hanney and West Hendred becoming part of the Vale of White Horse district in Oxfordshire, and the rest becoming part of the Newbury district of Berkshire.
