Fellside Recordings is a British independent record label, formed by Paul Adams and Linda Adams in 1976 in Workington, Cumbria, and still run by them.

Paul Adams toured semi-professionally with the Barry Skinner Folk Group in his teens. He and Linda married in 1974. Fellside started as a folk music label. They issued jazz under the name LAKE, and children's records as "small folk". Most of the Fellside catalogue was recorded and produced by Paul Adams. In 2007, BBC radio celebrated the company with a programme called "30 Years of Fellside". Three of their acts, John Spiers & Jon Boden, Nancy Kerr & James Fagan, and Kirsty McGee were nominated for BBC Folk Awards, and two of the acts were winners on the night. The label has won many awards including 12 from the Music Retailers Association. LAKE has won a BT British Jazz Award and Paul Adams was nominated for a BBC Jazz Award.

The Amazon website lists over 130 titles still in print, including albums by Spiers and Boden, Nancy Kerr & James Fagan, Dr Faustus, 422, Fribo, Hughie Jones, A. L. Lloyd, Peter Bellamy, James Keelaghan, Clive Gregson, The Queensberry Rules, Jez Lowe, Last Orders, Bram Taylor, and Grace Notes. Their anthologies have included songs by Maddy Prior, Richard Thompson, Frankie Armstrong, John Kirkpatrick and Martin Carthy. Fellside, along with Topic Records, are the two most significant and longest serving record labels for traditional music in the UK.

On the jazz side, LAKE Records's roster includes George Melly, Digby Fairweather, Ottilie Patterson, Phil Mason, John Hallam, The Fryer-Barnhart International All Star Jazz Band, The Savannah Jazz Band, Spats Langham, Debbie Arthurs and Keith Nichols.

In 2004, they started reissuing recordings from the defunct jazz label Record Supervision. This included the reissue of albums by Humphrey Lyttelton, Acker Bilk, Alex Welsh, Ken Colyer, Chris Barber, Terry Lightfoot, Sandy Brown, and Archie Semple. Singsong described this set of reissues as "A milestone in British jazz". They have a "Vintage" Series as well as a series recorded at the Dancing Slipper Jazz Club in Nottingham in the 1960s.
