Ribble Valley is a constituency[n 1] in Lancashire represented in the House of Commons of the UK Parliament since 2024 by Maya Ellis, of the Labour Party.

Much of the eastern part of the constituency lies within the historic county boundaries of the West Riding of Yorkshire.

Until 2024, with the exception of one year when, following a by-election, it was represented by a Liberal Democrat, the MP had been a Conservative; the lowest majority was 11.6% in 1997.

Six of the divisions on Lancashire County Council within the Ribble Valley constituency after the 2013 United Kingdom local elections were Conservative-held, with Labour having one.

1997–2010: The Borough of Ribble Valley, the City of Preston wards of Cadley, Greyfriars, Preston Rural East, Sharoe Green, and Sherwood, and the Borough of South Ribble wards of All Saints, and Samlesbury and Cuerdale.

In the run up to the 2010 general election, the Boundary Commission's Fifth Periodic Review of Westminster constituencies led Parliament to approve the creation of a new seat of Wyre and Preston North, to which the City of Preston wards, including Fulwood, were transferred.
