Marlow Moss (1889–1958) was a British Constructivist artist and a central figure in the development of European non-figurative art.

Moss’s importance to the history of modern art is arguably equal to that of her contemporary and friend Piet Mondrian, and yet her name has been relegated to obscurity. A pupil of Ferdinand Léger in Paris and one of the few women within the circle of influential artists in Paris in the late 1920s, Moss’s grid-like paintings, geometric sculptures and abstract reliefs sought to create a universal language of colour and form.

Today Moss’s work is beginning to be re-examined as a new generation of artists and art historians consider her contribution to modern art. Examples of this important artist’s work can be found in museums across Europe including at the Hague, and Tate, London.
