Alf Hurum (Kristiania, now Oslo, 1882 – 1972) was a Norwegian painter whose visual work is held in museums in Honolulu. He is more often remembered as a composer, responsible for works such as two violin sonatas, the suite Eventyrland and a symphony in D minor, but his painting forms an important part of his artistic career.
The son of Thorvald Hurum and Jakobine Olava Haslum, he studied composition at the Berlin Academy of Arts from 1905 to 1907, where his teachers included Max Bruch. He married Elizabeth Leslie Wight in Berlin in 1908. In 1934 he and his wife settled in Honolulu, Hawaii, the city where he spent his later decades.
In Honolulu he served as president of the Association of Honolulu Artists and was an honorary member of the Morning Music Club. His visual art is today represented in the Honolulu Museum of Art and the Bishop Museum.
