Sìleas (pronounced sheelis) is a Scottish harp duo. Patsy Seddon plays electric harp and gut-strung harp, and Mary Macmaster plays electric harp and metal-strung harp and they sing in both Gaelic and English. Together they make up part of the all-women folk band The Poozies.
The name of the band is explained on the back cover of the debut album Delighted with harps as follows: Sileas na Ceapaich was an 18th century Gaelic poet - her loving and eloquent praise of harp music led Patsy and Mary to take Sileas as their professional name.

They were inducted into the Scottish Traditional Music Hall of Fame in 2013.
