Ulf Kirsten (born 4 December 1965) is a former German footballer and manager, who played as a striker. Nicknamed Der Schwatte (dialect for "Der Schwarze", The Black One), he is the first player in the history to reach a total 100 caps playing with two different national teams. Kirsten's biggest success was the victory of the 1992–93 DFB-Pokal.
On club level, Kirsten played for only two teams: from 1983 to 1990 he was with Dynamo Dresden. In the East German Oberliga, he made 154 matches and scored 57 goals for Dresden.
Kirsten had an unusual build, measuring only 172 cm (5'8"), but weighing 81 kg (179 lbs). He had an unusually low centre of gravity, which enabled him to protect the ball in the box against much bigger defenders and turn around quickly for close-range shots. The playing style was often compared to that of Gerd Müller. In addition, despite his small height, Kirsten was also a feared header.
