Hedvig Mollestad Thomassen (born 4 February 1982) is a Norwegian guitarist, vocalist and composer. She is known for a series of album releases and collaborations with musicians like Jon Eberson, Jarle Bernhoft and Hilde Marie Kjersem.

"With Hedvig as a leader, the band seemingly denies an idea of hierarchy or leadership in a traditional sense, if there is such. While performing, each member of the trio has equal input. Subtle drum patterns by Bjørnstad, such as an improvised intro on Gimbal, cast a spell. When Brekken performs her intense and frenetic bass arpeggios, the audience keep their eyes fixed on the instrument and its player. With her interaction and directness, Mollestad is impressive, approaching you close enough to hear the strings ringing." – Louder Than War, review of Hedvig Mollestad Trio at Cafe OTO
