Hyndburn /ˈhaɪndbərn/ is a local government district with borough status in Lancashire, England. Its council is based in Accrington, the largest town, and the borough also covers the outlying towns of Clayton-le-Moors, Great Harwood, Oswaldtwistle and Rishton. The borough was created in 1974 and takes its name from the River Hyndburn. It had a population of 80,734 at the 2011 Census. Elections to the council are held in three out of every four years, with one third of the 35 seats on the council being elected at each election. Both the Conservative and Labour parties have controlled the council at different times, as well as periods when no party has had a majority.

Hyndburn borders the boroughs of Ribble Valley to the north, Burnley to the east, Rossendale to the south, and Blackburn with Darwen to the west.

The district was created on 1 April 1974 under the Local Government Act 1972, as a non-metropolitan district covering the territory of six former districts, which were abolished at the same time, plus a single parish from a seventh district:

The new district was given the name Hyndburn, taken from the River Hyndburn which passes through the district. The new district was awarded borough status on the day that it came into being, allowing the chairman of the council to take the title of mayor.

In 2007, the council proposed changing the name from Hyndburn to "Accrington and Districts", to aid recognition of the borough by those not familiar with the area. After a public consultation, the change of name did not go ahead.

Hyndburn Borough Council provides district-level services. County-level services are provided by Lancashire County Council. Altham is a civil parish, which forms a third tier of local government for that part of the borough.

In March 2010, Hyndburn Borough Council was voted the 10th best council in The Times "Best Public Sector Places to Work". The borough also made it to The Times Best Companies Guide.

The council has been under Labour majority control since the 2024 election.
