Staines was a rural district of Middlesex in England from 1894 to 1930.
It was created in 1894 based on the former Staines Rural Sanitary District.
Feltham became an independent urban district in 1904 so for the following 26 years the parish of Hanworth constituted an exclave.
The district was abolished in 1930. Thereafter the civil parishes of Ashford, Laleham and Stanwell saw their last 36 years as sub-entities of Staines Urban District, equally Littleton and Shepperton joined Sunbury-on-Thames Urban District. East Bedfont and Hanworth joined Feltham Urban District. Cranford and Harlington joined Hayes and Harlington Urban District, and Harmondsworth joined the Yiewsley and West Drayton Urban District.
