Hayde Bluegrass Orchestra is an internationally-touring English-language bluegrass ensemble from Oslo, Norway, who have been nominated for a Norwegian grammy, and featured as international showcase artists.

Hayde Bluegrass Orchestra performs with eight band members in the genres of folk, Americana, and bluegrass. The founding members were Joakim Borgen and Rebekka Nilsson, and the group's formation was inspired by the Belgian Oscar-nominated movie, The Broken Circle Breakdown. According to Lee Zimmerman of the website, Bluegrass Today:

"Ironically, the duo found certainly [sic] similarities between bluegrass and Norway’s native folk traditions, especially those sounds that connect them by way of British folk music and the traditional hymns. 'The fiddle — or more precisely the Hardanger fiddle, a Norwegian version that includes a double set of resonating strings — is very central to Norwegian folk music, along with a number of other harp-like string instruments,' Borgen explains."

John Lawless wrote of their Migrants album that the band often performs original compositions which blend "Appalachian and Nordic folk influences."

Arild Rønsen of Puls music magazine wrote of the band, "It is almost impossible to be more American than the Hayde Bluegrass Orchestra" and that they are among the first Norwegian artists to enter the Billboard bluegrass chart.

In 2024, co-founding member Joakim Borgen announced his departure from the group.

The band's album, Migrants, debuted at number four on the Billboard Bluegrass Chart on March 27, 2021.

Hayde Bluegrass Orchestra's 2021 album, Migrants, was nominated for a Norwegian grammy (also called a Spellemannprisen). In 2022, the band was an official showcase artist of the Folk Alliance International.
