Nesta Carter OD (born October 11, 1985) is a Jamaican retired sprinter who specialized in the 100 metres event. Carter was successful as part of the Jamaican 4 × 100 metres relay team, taking gold and setting successive world records at the 2011 World Championships and 2012 London Olympics.

In August 2010 he became only the fifth sprinter to run the 100 metres in less than 9.8 seconds.
