Apostolos "Apollo" Papathanasio (Greek: Aðüëëo ÐáðáèáíÜóéï or Áðüëëùíáò Ðáðáèáíáóßïõ) (born 15 March 1969 in Borås, Sweden) is a Swedish heavy metal vocalist, who is currently with the bands Firewind, Spiritual Beggars and Evil Masquerade. He has also sung for Meduza, Gardenian, and Richard Andersson's projects Majestic and Time Requiem.
In 2007, Papathanasio had to opt out of certain tour dates with Firewind. His position was temporarily filled by Henning Basse of Metalium. Apollo's latest release is "Fade To Black" (2009) with Evil Masquerade.
