Kitty Grande was a Norwegian Nazi collaborator who helped the notorious Rinnan Gang infiltrate resistance networks during the German occupation of Norway in the Second World War. Using the false identity Gerd Engan, she posed as a resistance member and gained the trust of Norwegians fighting against Nazi rule.

Born in 1919 near Trondheim, Kitty joined the fascist party Nasjonal Samling in 1941. The following year, she became an agent of Henry Rinnan's intelligence organisation, which operated under the German Security Service, or SD. Her apartment became a meeting place where unsuspecting resistance members were deceived into revealing information.

However, Kitty eventually turned against the Rinnan Gang and began warning some of its intended victims. In December 1942, she was arrested and later deported to Ravensbrück concentration camp. After the war, she was sentenced to 20 years of forced labour for her collaboration.
