Ulla Pirttijärvi is a Sami joik singer from the village of Angeli (Sami: Aŋŋel), Finland. She began her career with the music group Angelin Tytöt, but left soon after to pursue a solo career. She performs traditional joik music with Western arrangements of contemporary instruments.

Ulla Pirttijärvi was raised with joik music and chanting. As a young child, Ulla listened to her mother and uncle sing stories to her, and she chanted along; by age ten she was singing on her own. She then started performing in public with a group of young girls who called themselves Angelin Tytöt.
