The Corries were a Scottish folk group that emerged from the Scottish folk revival of the early 1960s. The group was a trio from their formation until 1966 when founder Bill Smith left the band, but Roy Williamson and Ronnie Browne continued as a duo until Williamson's death in 1990.

They are particularly known for the song "Flower of Scotland", written by Williamson, which has become an unofficial national anthem of Scotland.

In the early 1960s, Bill Smith (born in 1936 in Edinburgh - died March 1, 2025), Ron Cruikshank and Andy Turner had formed a trio called The Corrie Voices. The trio was named after Smith's daughter, Corrie Smith, but because a corrie is a deep bowl in a mountain, the name was particularly appropriate as it evokes imagery of the Scottish landscape. After Turner dropped out in 1962, Roy Williamson teamed up with Smith and Cruikshank to form the Corrie Folk Trio. Their first performance was in the Waverley Bar in St Mary's Street, Edinburgh. After a few weeks, Cruikshank left due to illness. They had already accepted an engagement at the Edinburgh Festival so Williamson suggested that Ronnie Browne should be brought in to make up the numbers.

The band added female Irish singer Paddie Bell to become the Corrie Folk Trio and Paddie Bell. The audience was only eight people for the debut of this line-up but by the end of the festival there was a full house at every performance.

Within a year of formation, they appeared on television. The BBC began a television series set in a folk club. The resident group on the Hoot'nanny Show was the Corrie Folk Trio. Another BBC series, The White Heather Club, began in 1958. It featured Andy Stewart, Jimmy Shand and his Band, Robin Hall and Jimmie Macgregor, and the Corries. While the rest of the show was set in a studio, the Corries were filmed in location: sea songs were sung in a harbour, and "The Braes o' Killiecrankie" was sung at the Pass of Killiecrankie.

In 1965, Paddie Bell departed, followed by Bill Smith in 1966. In the duo left behind, Williamson was a multi-instrumentalist while Browne handled lead vocals. They cancelled all engagements for a few months to practise intensely and, emerging under the new name, The Corries, they performed at the Jubilee Arms Hotel in Cortachy, Angus.

In 1969, "Flower of Scotland" featured on the Fontana release, "The Corries in Concert". The song was quickly adopted by world lightweight boxing champion Ken Buchanan, whose fans sang it on his entering the ring. It was then taken up by supporters of rugby union as the unofficial national anthem and is still used at Scotland's rugby internationals. "Flower of Scotland" has since been adopted as the national anthem at international football matches. 1974 saw the first release of a series of Live from Scotland albums on their own Pan-Audio / DARA label, all featuring live recordings from the group's famed tours of concert halls around Scotland, extending to a total of four volumes. The Flower of Scotland live performance from Live from Scotland Volume 1 was released as a single backed by Browne's song, "Roses of Prince Charlie", in several versions including one with special cover artwork for the 1974 FIFA World Cup campaign. The 1977 album, Peat Fire Flame, saw the group return to the studio album format, with a move towards love songs and celebrations of the landscape. By the 1980s however, the group would return to live albums for the rest of their recording career.

Roy Williamson suffered from asthma and before a series of concerts he would deliberately cease treatment to provoke attacks and gain temporary immunity. During the Corries' 1989 tour, Williamson's health went into decline and he was diagnosed with a brain tumour. He spent his last years living in Forres, close to where he spent his school years. He died on 12 August 1990.
