The 2015 Úrvalsdeild karla, also known as Pepsi-deild karla for sponsorship reasons, was the 104th season of top-flight Icelandic football. Twelve teams contested the league; the defending champions were Stjarnan, who had won their first ever league title in 2014 going unbeaten in the league. On 26 September FH were crowned champions after a 2–1 win over Fjölnir with one game to spare. This was FH's 7th league title. Keflavík and Leiknir R were relegated from the league. Keflavík had been in the league since 2004 but this was Leiknir R's first ever season in the top flight.
