The Unthanks (previously called Rachel Unthank and the Winterset, until 2009) are an English folk group from Northumberland. They made their debut performance at Towersey Village Festival in August 2004 and, on 11 May 2005, launched their debut album, Cruel Sister at Holmfirth Folk Festival. Cruel Sister received support from a number of DJs on BBC Radio 2 and was subsequently awarded Folk Album of the Year by Mojo magazine.

Their 2007 follow-up album, The Bairns, was nominated for the Best Album award at the BBC Folk Awards 2008 and also nominated for the 2008 Mercury Music Prize. The album debuted in the UK Top 200 Albums Chart at number 178 in the week after the Mercury prize award ceremony.

The band were nominated for three further BBC Folk Awards in 2008 (Best Band, Best Live Act, Horizon Award), and were successful in one category, receiving the Horizon Award at the ceremony in The Brewery, London.

Their third album, Here's The Tender Coming, was released in September 2009. Their fourth album, Last, is planned for release in spring 2011.

In a departure from their usual practice of showcasing material from their studio albums, the Unthanks performed two concerts at London's Union Chapel on 8 and 9 December 2010 consisting entirely of material written by Robert Wyatt and by Antony Hegarty of Antony and the Johnsons.
