Unitary authorities of England are local authorities that are responsible for the provision of all local government services within a district. They are constituted under the Local Government Act 1992, which amended the Local Government Act 1972 to allow the existence of counties that do not have multiple districts. They typically allow large towns to have separate local authorities from the less urbanised parts of their counties and provide a single authority for small counties where division into districts would be impractical. Unitary authorities do not cover all of England. Most were established during the 1990s and a further tranche were created in 2009. Unitary authorities have the powers and functions that are elsewhere separately administered by councils of non-metropolitan counties and the non-metropolitan districts within them.

The term "unitary authority" was first used in the Redcliffe-Maud Report in 1969 in its current sense of a local government authority which combines the functions of a county council and a district council. Strictly speaking, the term does not necessarily mean a single level of local government within an area, because in some cases there are also parish councils in the same area.

Although the term was not applied to them, county boroughs between 1889 and 1974 were effectively unitary authorities, that is, single-tier administrative units. Before 1889, local government authorities had different powers and functions, but from medieval times some cities and towns had a high degree of autonomy as counties corporate. Some smaller settlements also enjoyed some degree of autonomy from regular administration as boroughs or liberties.
