Aleksandar "Aleks" Vrteski (Macedonian: Александар Вртески; born 28 September 1988) is a former footballer who played as a goalkeeper for Stirling Lions.

Vrteski was signed from the Australian Institute of Sport and was the youngest player in the A-League for the 2006-07 season.

In October 2006, Aleks became the club's first-choice goalkeeper for the 06/07 season for the first few rounds but was replaced by Jason Petkovic.

Vrteski made a move overseas to play for Macedonian club FK Pobeda in 2007 and returned to Australia to sign for Perth Glory for the second time in his career in 2009, where he played as a backup to Tando Velaphi.

The 17-year-old made his debut for the Young Socceroos, keeping a clean sheet in a 4–0 win over Sri Lanka in Colombo to seal the U-20s' place in the Asian Youth Championships.
