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.

The discipline is, alongside the pole vault, one of two vertical clearance events in the Olympic athletics program. It is contested at the World Championships in Athletics and the World Athletics Indoor Championships, and is a common occurrence at track and field meets. The high jump was among the first events deemed acceptable for women, having been held at the 1928 Olympic Games.

Javier Sotomayor (Cuba) is the current men's record holder with a jump of 2.45 m (8 ft 1⁄4 in) set in 1993 – the longest-standing record in the history of the men's high jump. Stefka Kostadinova (Bulgaria) has held the women's world record of 2.09 m (6 ft 10+1⁄4 in) since 1987, also the longest-held record in the event.
