Alexandros "Alex" Margaritis (Greek: Αλέξανδρος Μαργαρίτης; born 20 September 1984) is a Greek-German racing driver who is best known for competing in the German-based Deutsche Tourenwagen Masters touring car championship.

Margaritis had his first experience of karting in 1996, and in 1997, he competed in the ICA Junior class, in which he secured the championship runner-up position.

On 27 February 2008, Margaritis announced his intention to leave the DTM and seek a position in another championship or category, citing as a primary factor the handicap of competing in year-old cars against machinery of factory specification.

[1] In 2008, Margaritis switched his focus to GT cars: He competed in the 24 Hours of Spa for Phoenix Racing.

After one season without racing in major series, Margaritis participated in the newly created FIA GT1 World Championship.
