Ari Freyr Skulason is an Icelandic international football player who plays for Lokeren in Belgium. He previously played at senior level in Iceland and Sweden, and was also a youth player in the Netherlands.

Ari started his career at Valur. He then went to the Netherlands as a sixteen-year-old and spent two seasons with SC Heerenveen before being released at the end of 2005 after not being able to make the first team. He returned to his old club Valur where he played half a season before signing with Allsvenskan club BK Hacken. Hacken managed to progress into the main competition after Ari scored the winning goal against Dunfermline Athletic F.C.. After the club failed to get promoted he signed with Allsvenskan club GIF Sundsvall at the end of the year. At the start of the 2012 season he became captain of the club.On 19 July 2013 it was announced that the clubs had reached an agreement for his semi-immediate transfer. On 27 July he played his last game for Sundsvall, scoring two free-kick goals in a 3-3 draw against GAIS.

After being capped at various youth levels he got to make his debut for the Icelandic national team in 2009 against Iran. In 2012 he started getting more frequent callups from new national team manager Lars Lagerback.Despite Ari having been playing as a midfielder for his club side he was nonetheless picked in the Iceland squad as a left-back and has been the first-choice left-back in the national team during most of the 2014 World Cup qualifiers. Consequently Ari felt that he needed to change his position at club level and asked to be bought as a left-back when he was sold in July 2013, so he could play that position at club level to be able to hold his place as the first-choice left-back in the Iceland squad, despite the fact that he has been praised as a central playmaker of high quality.He was selected for EURO 2016.
