Anna Thommesen née Jepsen (1908–2004) was a self-taught Danish textile artist and painter.
In an austere, geometrical style, she wove tapestries and rugs on a loom she developed herself.
After the marriage was dissolved in 1940, she married the sculptor Erik Thommesen, with whom she had three children: Lene (1942), Klaus (1945) and Viggo (1949).
After leaving her daughter Annelise to her first husband after the divorce, she married Thommesen, the son of the owner of the factory where she was working.
Inspired by nature, her abstract depictions were executed with intuitive perfectionism, demonstrating her interest in clarity and purity and reflecting the constructivist trends of the times.
