Marius Martinussen is a Norwegian contemporary artist (born 1978 in Kristiansand). He studied at Einar Granum Art School and Trondheim Academy of Fine Art, working primarily with painting and lithography.

With over 25 years in the art world and a unique and experimental style, he plays a significant role in Norwegian contemporary art. Martinussen has received numerous prestigious art grants for his artistry and has been selected for both national and international exhibitions, such as Kunstnernes Hus' Autumn Exhibition (2004 and 2011) and the International Billboard Painting Festival, Viborg, Denmark (2012).

Through his paintings, Martinussen presents a striking and, at first glance, abstract form that can quickly become figurative. This can evoke streetlights, graffiti, or old, dilapidated, and scratched walls. Vibrant use of color, organic forms, and layering take us to contrasts within the urban landscape. Thus, his expression can be seen as personal and storytelling as much as abstractly charged and emotionally evocative.

The colors that dominate his works, such as magenta and turquoise, often contrast against a subdued and gray background, frequently employing broad brushstrokes against a soft and detailed backdrop. With a rich and varied painting technique, he creates depth in his works that captures the eye.

Martinussen's contrasting use of color can recall some of Damien Hirst's earlier colorful paintings like "Beautiful, amore, gasp, eyes going into the top of the head and fluttering painting," 1997, or can be associated with Marianne Heske's La Vie En Rose, 2017. It is not only his use of color but also methods such as airbrush painting that indicate he is inspired by the pop art movement.

His works have been acquired by institutions such as the Norwegian Arts Council, StatoilHydro, Ernst & Young, Handelsbanken, and as a wedding gift by Crown Princess Mette-Marit and Crown Prince Haakon.
