Blanka Vlašić is a Croatian former track and field athlete who specialized in the high jump. She is a two-time world champion and double Olympic medallist who ranks as the joint second highest female jumper of all time with her personal best of 2.08 m. She is the Croatian record holder in the event, and the former indoor world champion.

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.
