Knattspyrnufélagið Hörður, commonly known as Hörður or Hörður Ísafjörður, is an Icelandic multi-sport club from the town of Ísafjörður. It was founded in 1919 as a football club^[1] but since 1933 it has fielded other departments, most prominently in handball, track & field, skiing and Icelandic wrestling.^[2][3][4]

Knattspyrnufélagið Hörður was founded on 27 May 1919 as a football club with Þórhallur Leósson being its first chairman.^[5] Its first official game was against Fótboltafélag Ísafjarðar on 17 June 1921. In 1933 it started a department in women's Handball and in 1937 a track & field department.^[6] At its peak in the 1940s it was the largest sports club in the Westfjords.^[7][8]

Hörður has periodically fielded a men's handball team during its history.^[14] In February 2020, Þór Akureyri demanded that Hörður would pay 400.000 ISK in travel expense of Þór's trip to Ísafjörður for their September game in the Icelandic Cup. In the Cup, teams split all the income and cost of games, including travel expense of the away team, and Þór stated that their total travel expense was 800.000 ISK. The board of Hörður strongly objected as its own travel expense to Akureyri in January where they faced Þór's reserve team had not exceeded 120.000 ISK.^[15][16] Two days later, the clubs reached an undisclosed settlement and the Icelandic Handball Association announced it would review its rules regarding the settlement of cup games.^[17]

Although it finished last in the third-tier 2. deild karla in 2019–20,^[18][19] Hörður was offered a seat in the second tier 1. deild karla for the 2020–21 season^[20] where they finished in 8th place.^[19]

In July 2021, the club signed Japanese national team player and Olympian Kenya Kasahara.^[21][22] On 8 April 2022 the team won the second-tier 1. deild karla and achieved promotion to the top-tier Úrvalsdeild karla for the first time in its history.^[23] After one season in the Úrvalsdeild, Hörður was relegated back to 1. deild after failing to register a win in the league.^[24]
