'Lark' (iii) was a British operation by the Special Operations Executive to land arms and equipment in the Trondheim area of German-occupied Norway in preparation for the resurrection of this series of operations (3/11 January 1943).

The two-man party of J. Pevik and N. U. Hansen departed the UK by sea on 3 January and returned on 11 January after delivering about 1,100 lb (500 kg) of material to three sites in the area of Trondheim.
