Per Karlsson (born 2 January 1986 in Stockholm) is a Swedish footballer. He came through the ranks of Solna club Vasalunds IF and was picked up by AIK as a teenager. After coming through the academy at AIK he secured a regular starting-spot at AIK in late 2004, but broke his leg in beginning of 2005 against Väsby United which ruled him out for much of that season. When he became fit again he was loaned out to Väsby United, which now was a feeder club to AIK, for the 2006 season. However he broke his arm this time and wasn't able to play any matches for them. During the 2007 season he was loaned out to Åtvidabergs FF in Superettan and was finally able to play a whole season. During 2008 he once again became a member of the regular starting eleven at AIK, which he lost after his leg break in 2005.
