Knut Steen (19 November 1924 – 22 September 2011) was a Norwegian sculptor. He spent much of his life living between Sandefjord, Norway, and Carrara, Italy. He began sculpting in 1946 and worked with a range of materials including marble, granite, bronze, steel and concrete. In 2011 a small museum was opened in Sandefjord to display some of his work. The collection holds 12 marble sculptures and four works.
