Jóhan Martin Christiansen (b. 1987) is a visual artist from the Faroe Islands and is currently working and living in Copenhagen, Denmark. He holds an MFA in Visual Arts from Malmö Art Academy (2014) and was part of the Of Public Interest Lab program at the Royal Institute of Art in Stockholm 2023-24.

Christiansen primarily works with sculpture and installations. The pieces come into being in the balance of taking a formal conceptual approach while keeping channels open to the poetic sphere allowing material, matter and meaning to mutate in free interplay. His work deals with subjects such as natural and constructed environments, queer body memory, the baroque, and pop music.

Christiansen has received honorary grants for his work and working scholarships from the Danish and Faroese Art Foundation amongst others. He has been teaching at the University of the Faroe Islands and at the Royal Danish Academy of Fine Arts.

Christiansen have had numerous exhibitions on the Faroe Island, Denmark, Sweden, Finland, United States, Bulgaria, Iceland, Japan, Greece, Greenland, the Republic of San Marino, Latvia.

In 2023 he founded the artist run project space Bonne Espérance in Copenhagen.
