Mari Silje Samuelsen (born December 21, 1984) is a Norwegian violinist.
Samuelsen grew up in Hamar, and began playing violin at age three at a local music school outside the city. By age four, she became a student of violinist Arve Tellefsen, who called Mari and her brother Håkon Samuelsen “among the greatest string music talents in Norway”. She studied with Tellefsen in Oslo, and played with him for almost 10 years.
Samuelsen later studied at the Barratt Due Institute of Music in Oslo under the tutelage of violinist Stephan Barratt-Due. For the last ten years, she has been a student of the Russian professor and violinist Zakhar Bron. She earned two master’s degrees at Zurich University of the Arts in Switzerland in 2012.
