Alan Fonteles Cardoso de Oliveira[1] (born 21 August 1992) is a Paralympian athlete from Brazil competing mainly in category T44 sprint events.

Immediately after the race Pistorius caused controversy by criticising the blades Oliveira had used, claiming they were too long and artificially increased his stride length, giving him an unfair advantage.

Pistorius' complaint was denied at that time by the International Paralympic Committee, which stated all athletes were measured prior to the race by a classifier and all blade lengths were approved for competition.

In July 2013 at the Paralympic Anniversary Games in London Oliveira became world's fastest double amputee athlete when he completed the T43 100m race in a time of 10.57 beating his previous record of 10.77 which he had set in Berlin in June 2013.

[8] At the 2016 Summer Paralympics, held in Rio de Janeiro in his home country of Brazil, Oliveira failed to reach the final of either the 100m or 200m races in the T43 class.
