Ploughley was a rural district in Oxfordshire, England, from 1932 to 1974.^[1] It entirely surrounded Bicester but did not include it.

It was created in 1932 from parts of the abolished Bicester Rural District, Headington Rural District and Woodstock Rural District, along with a couple of non-urban parishes from Bicester urban district.

In 1974 it was abolished under the Local Government Act 1972 and now forms part of the Cherwell district.
