Íþróttafélagið Þór, usually known by the names Þór Akureyri or Thór, was first established back in June 1915 by Frederick Einarsson. Based in the town of Akureyri, they are nicknamed Þórsarar and were originally founded as a youth team. As a sports club, Thór are also competitive in handball, basketball and judo, as well as women's football. Their main local rivals in all sports are KA Akureyri.
Throughout history, Thór have spent a significant amount of time in Icelandic football's second tier, 1. deild, and have struggled to fully establish themselves as a top tier side. To date, the team have been unable to claim any of Iceland's major honours and have rarely been able to compte seriously for them.
In 2010, they finished the 1. deild season as runners up, behind Víkingur Reykjavík. As a result, they gained promotion back to the top flight, the Úrvalsdeild, for the first time since 2002. The 2011 season brought about Thór's closest brush with a major trophy so far. After eliminating teams like ÍBV and Vikingur Reykjavík, they made it to the final of the Icelandic Cup, where they met KR. Unfortunately, they lost the match 2-0 and had to settle for being the competition's runner up. However, because KR also won the league and entered the UEFA Champions League, Thór were granted entry into the preliminary rounds of the UEFA Europa League.
Icelandic international midfielder, Aron Gunnarsson, was a product of the club's youth academy and played for the first team between 2005 and 2006. Other notable former players include another Iceland international, Lárus Sigurðsson, who enjoyed two seperate spells with the side, and Seán Webb, who earned four caps for Northern Ireland.
Thór's home games are held at Þórsvöllur, which is currently able to hold up to 1,550 spectators for football matches.
