'Fifth Enemy Offensive' was the Yugoslav designation for the German-led undertaking, also known to the Yugoslavs as the Battle of the Sutjeska and to the Germans as 'Schwarz' (ii), against the partisan forces of Josip Broz Tito (20 May/15 June 1943).

The operation followed immediately after the 'Fourth Enemy Offensive' (Battle of the Sutjeska and 'Weiss' [ii]), and was designed to include the complete encirclement of the partisan forces in south-eastern Bosnia and northern Montenegro.
