Jan Niklas Patrik Sjöberg is a Swedish former high jumper. He broke the world record with 2.42 m in Stockholm on 30 June 1987. This mark is still the European record and ranks him third on the world all-time list behind Javier Sotomayor and Mutaz Essa Barshim. He is also a former two-time world indoor record holder with marks of 2.38 m (1985) and 2.41 m (1987). He is the 1987 World Champion and a three-time Olympic medallist.

The high jump is a track and field event in which competitors must jump unaided over a horizontal bar placed at measured heights without dislodging it. In its modern, most-practiced format, a bar is placed between two standards with a crash mat for landing. Since ancient times, competitors have introduced increasingly effective techniques to arrive at the current form, and the current universally preferred method is the Fosbury Flop, in which athletes run towards the bar and leap head first with their back to the bar.
