Sweden competed at the 2012 Summer Olympics in London, from 25 July to 12 August 2012. Swedish athletes have competed at every edition of the Summer Olympic Games in the modern era, except for the 1904 Summer Olympics in St. Louis. The Swedish Olympic Committee (, SOK) sent a total of 134 athletes to the Games, 55 men and 79 women, to compete in 20 sports. For the second consecutive time in its Olympic history, Sweden was represented by more female than male athletes.
Sweden left London with a total of 8 Olympic medals (1 gold, 4 silver, and 3 bronze), tying with Tokyo and Atlanta for the overall highest medal count. Two medals each were awarded to athletes in sailing and wrestling, and one each in equestrian, handball, and triathlon. For the first time since 1992, Sweden won more than a single Olympic medal in Greco-Roman wrestling.
Among the nation's medalists were Star sailors Fredrik Lööf and Max Salminen, who together won Sweden's only gold medal in London, the nation's first in eight years. Lisa Nordén, who finished eighteenth in Beijing, became the first Swedish athlete to win an Olympic medal in women's triathlon. Meanwhile, equestrian eventing rider Sara Algotsson Ostholt won the nation's only silver medal in her sport. Sweden's team-based athletes also equalled their previous best Olympic results after 12 years, as they achieved a silver medal in men's handball. Several Swedish athletes narrowly missed out on the medal places in their events, including long jumper Michel Tornéus, singles sculls rower Lassi Karonen, swimmers Sarah Sjöström and Therese Alshammar, and sprint kayakers Sofia Paldanius and Anders Gustafsson.
Sveriges Olympiska Kommitté (SOK) selected a team of 134 athletes, 55 men and 79 women, to compete in 20 sports; it was the nation's fourteenth largest team sent to the Olympics outside the host nation. Handball and women's football were the only team-based sports in which Sweden had its representation in these Olympic games. There was only a single competitor in archery, badminton, mountain biking, judo, and triathlon. Sailing was the largest team by individual-based sport, with a total of 14 competitors. Sweden also marked its Olympic return in men's handball after a twelve-year absence.
The Swedish team featured past Olympic medalists, four of them from Beijing (road cyclists Gustav Larsson and Emma Johansson, sailor Fredrik Lööf in the Star class, and equestrian show jumper Rolf-Göran Bengtsson, who competed at his fifth Olympics). For being the oldest and most experienced athlete, Bengtsson, at age 50, was Sweden's flag bearer at the opening ceremony. Table tennis player Jörgen Persson became the second Swedish athlete to compete in seven Olympic games, tying the record set by pistol shooter and former Olympic record holder Ragnar SkanÃÂ¥ker. Dressage rider Tinne Vilhelmsson-Silfvén, and butterfly swimmer Lars Frölander, along with Lööf, competed at their sixth Olympics. Meanwhile, four other Swedish athletes made their fifth Olympic appearance, along with Bengtsson: equestrian eventing rider Linda Algotsson, freestyle swimmer Therese Alshammar, and sprint kayak pair and double Olympic medalists Henrik Nilsson and Markus Oscarsson. Gymnast Jonna Adlerteg, at age 17, was the youngest athlete of the team.
Other notable Swedish athletes featured sprint kayaker and world champion Anders Gustafsson, butterfly swimmer and triple European champion Sarah Sjöström, tennis doubles specialist Robert Lindstedt, triathlete and former World Series champion Lisa Nordén, and equestrian eventing rider Sara Algotsson Ostholt, who made her Olympic comeback in London after a twelve-year absence.
