The Trio Bulgarka (Трио Българка), also known as Three Golden Coins, previously known as Bulgarka Folk Trio, is a Bulgarian vocal ensemble.

They gained international prominence through their contributions to the groundbreaking 1975 Bulgarian folk music album "Le Mystère des Voix Bulgares, Volume 1", originally released on the Swiss label Disques Cellier and later reissued on British 4AD Records.

The trio comprises Stoyanka Boneva from Pirin, Yanka Rupkina from Strandja and Eva Georgieva from Dobroudja. Their diversity of regional backgrounds enabled them to create a unique sound to their music. They signed to record labels Bulgaria Balkanton and Hannibal in 1987. Two years later they featured on "The Sensual World" album by Kate Bush on the songs “Deeper Understanding”, “Never Be Mine”, and “Rocket’s Tail”. In 1993 they appeared on another Kate Bush album, "The Red Shoes", on the songs “You’re the One”, “The Song of Solomon”, and “Why Should I Love You?”, which also featured Prince. The trio have since concentrated on solo projects but often re-form for concert appearances.
