UMFK Esja, also known as Esja Reykjavík, was an ice hockey team in Reykjavík, Iceland, founded in 2014.[1] The team played in the Icelandic Men's Hockey League from 2014 to 2018, winning the national championship in 2017.[2] On 27 February 2018, the club announced it would not field a team for the upcoming 2018–2019 season due to the refusal of the Ice Hockey Association of Iceland and Reykjavík's Athletic Federation to allow the club to start a junior program, which they claimed was essential for the club's future.[3]
