Thomas Morgenstern (born 30 October 1986) is an Austrian former ski jumper. He is one of the most successful contemporary ski jumpers, having won the world cup twice; the Four Hills Tournament and the Nordic Tournament once each; the Grand Prix three times; and 12 gold medals at world championships and Olympic games. After a career spanning twelve years at World Cup level, Morgenstern retired in September 2014.
At the start of the 2003–04 season, Morgenstern suffered a violent accident in Kuusamo, in which he was hit by a gust of wind just after takeoff, forcing him to flip over in mid-air and land hard on his back. He only sustained minor injuries, and managed to recover quickly to continue his success. He was second overall to Sigurd Pettersen during most of that season's Four Hills tournament, finally ending up in fourth place. He won his first team medal with a 3rd place at the Ski-Flying World Championships.
In the 2006–07 season, he won the large hill team event at the Nordic World Ski Championships. Further, by reaching the 3rd place in the normal hill event he won his first individual medal at world championships. As in 2003, Morgenstern won the Ski jumping Grand Prix.
The season 2010–11 again started very successful by winning four of the first six competitions. Morgenstern further won the Four Hills Tournament for the first time in this season. In January 2011, he won his first ski flying event in Harrachov, and fixed his second victory of the ski jumping world cup with a 5th place at the ski flying competition in Vikersund on 13 February. At the 2011 FIS Nordic World Ski Championships in Oslo he won gold on the normal hill. It was his first gold medal in an individual event at world championships. In the following he further won gold medals in the team events (normal hill and large hill), both times together with Andreas Kofler, Martin Koch and Gregor Schlierenzauer, as well as the silver medal in the individual large-hill event.
On 10 January 2014 he suffered serious head injuries during training for the ski flying event in Bad Mitterndorf. He recovered in time to take part in the 2014 Winter Olympics in Sochi, where he placed 14th in the normal hill and 40th in the large hill men's individual ski jumping events.
On September 26, 2014 Morgenstern announced his retirement from competitive ski jumping.
