IF Elfsborg (Swedish pronunciation: [ˈɛlfsbɔrj]) is a Swedish football club located in Borås. The club has won five national championship titles, the latest in 2006, and two national cup titles. Currently playing in the highest Swedish league, Allsvenskan. Elfsborg is based at Borås Arena. The club is affiliated to the Västergötlands Fotbollförbund.

Borås Fotbollslag was formed on June 26, 1904, by a group of youngsters. In 1906 the name was changed to IF Elfsborg, because the founders felt there were too many teams with 'Borås' in their name. In 1926 Elfsborg won Västsvenska Serien, and defeated Halmstad BK in the play off, and was promoted to Allsvenskan for the first time. During the 1930s Elfsborg managed to build a very strong team led by striker Sven Jonasson, who appeared in both the 1934 and 1938 World Cup. In 1936 Elfsborg won Allsvenskan for the first time, and two more titles followed soon after (1939 and 1940). During this period Elfsborg had as many as seven players in the Swedish national team.

Daniel Tjernström, born 19 February 1974 in Karlskoga, Sweden, is a professional footballer with Swedish top side AIK. He is currently the captain of the team, and is one of AIK's most successful players. He was voted Most Valuable Player by the AIK fans in 2005, when he spearheaded the quick return to the Allsvenskan, as well as in 2006. His main strengths are his ability to read the game and his tireless running. His main weaknesses are that he is extremely left-footed and that he is relatively slow. Especially the later quality has stopped him from getting capped more than five times with the Swedish national team (97-99).
