Buckinghamshire is a unitary authority area in the ceremonial county of Buckinghamshire, England. It covers about four-fifths of area of the ceremonial county and about two-thirds of its population; the City of Milton Keynes accounts for the remainder. As a unitary authority area, it is both a non-metropolitan county and a non-metropolitan district.

The district is administered by Buckinghamshire Council. The council was formed in 2020, following the abolition of the previous county council, Buckinghamshire County Council, and the four district councils covering the area.
