Ulrikke Eleonore Sigwardt Greve (1868–1951) was a leading Norwegian textile artist in the early 20th-century, excelling in tapestry work.
Soon one of the country's best weavers, she taught in rural Nordfjord until she was invited in 1900 to head the weaving school at the Arts and Crafts Museum in Trondheim.
She gained a reputation as an outstanding proponent of weaver-artist collaboration, thanks to her expertise in regard to yarn, colours and technique.
Her most important work Blaa skog was the result of her collaboration with Arne Kavli which bordered on Impressionism, transforming Norway's traditional weaving designs into the world of contemporary art.
Further work in collaboration with Axel Revold proved increasingly unnerving as she found it difficult to comply with his wishes.
