Crowthorne is covered by two Borough councils, Bracknell and Wokingham, and three Parish Councils, Crowthorne, Wokingham Without and Finchampstead :-
Crowthorne Parish Council is one of the three Parish councils charged with the management of the Crowthorne community.
The Wokingham Without Parish Council exists to serve the community of Wokingham Without which has approximately 3,000 households. Wokingham Without is situated between the towns of Wokingham, Crowthorne and Finchampstead.
Finchampstead Parish has a population of around 12,000 and covers a large area comprising both rural and residential areas. It runs from the Inchcape Garage in Finchampstead Road in the north, to the Blackwater River in the south and from Crowthorne Station in the east to the Reading Road in the west.

The Arborfield Garrison Resident's Action Group (AG-RAG) represents the civilian residents who mostly live in the southern part of Arborfield. Although this area is adjacent to the Arborfield Garrison itself, the AG-RAG does not represent the views or interests of the MoD or the Military Commander of the Arborfield Garrison.
The Wokingham Society is a Civic Society established in the 1960s to combat the threat to the town's buildings and facilities from widespread and often thoughtless redevelopment. Although it has not always been possible to prevent the loss of individual landmarks, the Society's voice has been significant in helping to preserve many local historical features and to ensure that development has been sensitive to the town's heritage.
