Andreas Raelert (born 11 August 1976) is a German triathlete.
On 10 July 2011, Raelert broke the world record time for an Ironman Triathlon distance race at the at Challenge Roth event in Roth, Germany. Finishing in a time of 7 hours, 41 minutes and 33 seconds, beating Marino Vanhoenacker's record time of 7:45:58 set just a week before.
