Sidsel Hanum (b. 1955 in Hamar) is a Norwegian ceramist who lives and works at Borøya, an island in the inner Oslofjord. Working mainly with porcelain, Hanum explores the possibilities and limits of clay. These explorations have resulted in intricate yet delicate nature-inspired objects, and in simple yet technical demanding oval forms.

Sidsel Hanum attended Statens håndverks- og kunstindustriskole (now a part of the Oslo National Academy of the Arts) during the period 1976-81. Hanum has participated in numerous group exhibitions in Norway and abroad (London, Munich, Chicago and New York). She has also had several solo exhibitions at, among others, Lillehammer Kunstmuseum, Galleri Format Oslo, Kunstnerforbundet and Sørlandets Kunstmuseum. In 2010, she was rewarded the Craft Award (Kunsthåndverksprisen).
