The 2006–07 Four Hills Tournament was a series of ski jumping competitions held in the traditional venues of Oberstdorf, Garmisch-Partenkirchen, Innsbruck and Bischofshofen, located in Germany and Austria. The tournament was part of the 2006–07 Ski Jumping World Cup and points scored in each of the four competitions also counted towards the World Cup rankings. Before the tournament started on 28 December 2006 the World Cup leader was Simon Ammann.
Norwegian Anders Jacobsen won the tournament, after finishing on the podium in both hills in Austria and never finishing worse than fifth on any of the four hills. He thus became the first debutant since Toni Nieminen in 1991–92 to win the tournament.Gregor Schlierenzauer, who turned 17 on the day of the final event in Bischofshofen, won the first and last event, but finished over 15 points behind after 11th place in Innsbruck.
Results are listed for the top 15 skiers, as well as skiers among the top six in the overall World Cup before the tournament, former overall World Cup winners, former Four Hills Tournament winners, former world record holders, and former World or Olympic champions.
Austrian junior world champion and newcomer Gregor Schlierenzauer, who with his 16 years of age was one of the key factors and surprises of the pre season also excelled in the first day of the Four Hills Tournament. His first jump of the day (135.5 metres) was the furthest jump in competition, with only World Cup leader Simon Ammann and Martin Koch able to finish 0.5 metres short. While Andreas Küttel set a new record for the day in the second jump when he reached a distance of 136.5 metres Schlierenzauer again showed his skills and his capability of keeping his nerves in control when he jumped 142.0 metres, just 1.5 metres short to equalise the hill record set by Sigurd Pettersen in 2003. Switzerland's Andreas Küttel claimed the second position, but trailed by 9.5 points, while Adam Małysz of Poland finished in third position, 6.2 points behind Küttel. The win was Schlierenzauer's third win in five World Cup meetings. 2005–06 shared winners Janne Ahonen and Jakub Janda only finished in seventh and 21st position respectively, while Olympic champion Thomas Morgenstern just reached a top 10 ranking. With his win Schlierenzauer not only took the lead in the Four Hills Tournament, but he also overtook Ammann to lead the overall World Cup.
