Einar Örn Birgisson (27 September 1973 – 8 November 2000) was an Icelandic footballer and businessman.
He had his breakout season in 1997, finishing tied for third most goals in the Icelandic top-tier league.
He left the club in April 2000 after a disagreement with manager Pétur Pétursson and later sued KR for the remainder of his salary.
