At the 2010 Winter Olympics, Hirscher placed fourth in the giant slalom and fifth in the slalom at Whistler Creekside. He placed fourth in the giant slalom at the 2009 World Championships, but broke his ankle the weekend preceding the 2011 World Championships, which ended his 2011 season.
Returning after injury, Hirscher had his best season to date in terms of wins in 2012 with 9 victories and a total of 14 podiums, all in the two technical events (except for one third place in the season's last Super G). He won the World Cup overall and giant slalom titles, and placed third in the slalom.
In October 2012, Hirscher was awarded the Skieur d'Or Award by members of the International Association of Ski Journalists for his performances during the previous season.
Hirscher won the overall World Cup title again in 2013 with 6 victories; he also won the slalom title and was runner-up in giant slalom. Hirscher scored a total of 18 podium finishes out of 19 races in the two technical events. The only race in either slalom or giant slalom where he finished outside top 3 was the giant slalom in Adelboden. In that particular race Hirscher was leading after the first run, built up his advantage to over a second in the second run, but nearly fell several gates before the final, thus missing the win and finished only 16th. He became the first male racer to retain the overall World Cup title since fellow Austrian Stephan Eberharter in 2002 and 2003 and the first to win it three years in a row since American Phil Mahre did so in 1981, 1982 and 1983.
In 2015 Hirscher dominated the giant slalom standings with 5 wins, including a winning margin of 3.28 seconds in Garmisch, and won the GS title for the second time. With his slalom win in Zagreb he became the most successful Austrian male World Cup slalom skier surpassing Benjamin Raich. In the final race of the season in Meribel he overturned a 55-point deficit in the standings by winning his 16th World Cup slalom, and with it won the slalom title for the third year in a row. Hirscher became the first male alpine skier to win the overall World Cup title four times in a row.
In 2016 Hirscher became the most successful Austrian male World Cup GS skier by winning in Beaver Creek, Colorado, surpassing Benjamin Raich and Hermann Maier. With his GS win in Alta Badia, Italy (his 3rd consecutive win at that venue), he became Austria's most successful World Cup GS skier overtaking Annemarie Moser-Pröll. Another GS win in Kranjska Gora, Slovenia confirmed Hirscher as the GS title winner with one race to go. To wrap up an amazing season with 8 wins and 19 podiums Hirscher also won the men's overall World Cup title, his 5th consecutive overall title, a feat never before achieved by a male skier. His points total also enabled Austria to narrowly beat France in the men's nations cup by 201 points, the narrowest winning margin for many years. Hirscher was the only Austrian male skier to win a race in the entire season, and scored 30.9% (1795 out of 5804) of the Austrian men's nations cup points.
In 2017 Hirscher won the first slalom of the season on November 13 in Levi, Finland and equalled Pirmin Zurbriggen's win total of 40, putting him equal 5th in the standings. He also achieved his 93rd podium, surpassing Benjamin Raich's total. On the 18th December he won the fourth giant slalom of the season in Alta Badia having finished second in the three preceding giant slalom races, equalling Alberto Tomba's 4 wins at the venue, and with it became the 5th most successful male World Cup winner. On January 7 Hirscher achieved his 100th podium from 191 starts (a ratio of 52.3%) with a 2nd place finish in the giant slalom in Adelboden. On January 29 Hirscher won the GS in Garmisch, achieving his 20th GS and 43rd World Cup win, and with it attained Austria's 100th GS win for men.
At the FIS Alpine World Ski Championships 2017 in St. Moritz, Switzerland Hirscher won gold in the GS and slalom, and silver in the combined, missing the gold by just 0.01 seconds. He was the most successful athlete at the championships.
On March 4 in Kranjska Gora, Slovenia, Hirscher won his third GS race of the season and with it secured his 4th GS World Cup title and his 6th overall World Cup title, the only male skier in history to do so. One day later Hirscher finished fourth in the slalom and with it secured his fourth World Cup slalom title.
Even though his titles were secured, Marcel Hirscher pushed hard and ended his Giant Slalom season with another win in Aspen. It became his most successful season in the discipline, as he climbed on the podium in every single classic Giant Slalom, including four wins, took the World Champion title and clinched the discipline globe.
