Emma Mathilda Aicher (born 13 November 2003) is a Swedish-born German World Cup alpine ski racer. She competes in all disciplines and represents Germany.
Aicher's achievements include two Olympic silver medals and a bronze medal in the World Championships. Her first World Cup podium came in a downhill in February 2025. One day later, she won her first race, also a downhill.
At the 2026 Winter Olympics in Italy, Aicher won two silver medals; one in downhill and the other in team combined with Kira Weidle-Winkelmann, with Aicher skiing the slalom portion.
A daughter of a Swedish mother and a German father, Aicher grew up in Sundsvall, Sweden, where she started skiing and joined the local ski club. Later, she moved with her parents to Engelberg, Switzerland, and then back to Sundsvall. She holds both Swedish and German citizenship.
In March 2019, Aicher won the U16 Slalom of the FIS Children Cup, representing Sweden. Later that year, she took part in her first FIS races. In 2020, she joined the German Ski Association, for the reason of "better training opportunities in the Alps". Making her debut in the Europa Cup in December 2020, she took her first podium in slalom in January 2021.
Three weeks later, Aicher represented Germany at the World Championships, where she won bronze in the team event. That November on her eighteenth birthday, she made her World Cup debut in a parallel giant slalom at Lech/Zürs, Austria.
Without a top 30 result in World Cup downhill through January 2025, Aicher finished sixth in both downhill and super-G at the World Championships in early February. Three weeks later at a pair of downhill races in Kvitfjell, Norway, she gained her first World Cup podium and followed it up with a victory the next day.
On 8 February 2026, Aicher won a silver medal in the downhill Alpine skiing event at the Olimpia delle Tofane in Cortina d'Ampezzo at the 2026 Winter Olympics with a time of 1:36.14. Two days later, she achieved the top time of 44.38 in the slalom event of alpine combined at the same skiing center, securing another silver medal with teammate Kira Weidle-Winkelmann.
