Joachim Brøchner Olsen (born 31 May 1977) is a Danish former politician and former world class shot putter.

Nevertheless, he received worldwide attention after he wrote in a chat room that the winner of the final, Arsi Harju had failed a doping test.

The rumour was false, and the incident caused the Danish National Olympic Committee to send Joachim B. Olsen home prior to the closing of the Games.

In 2003 a hand injury held him back, but a revised training plan removed the pain in his wrist.

Thus Olsen was ready for a comeback in 2004, and at the 2004 IAAF World Indoor Championships he won a Bronze medal - a placement he repeated at the Olympic Games in Athens.

A month later, at the World Indoor Championships, he managed to win a bronze medal with a throw of 21.16 metres.

On 22 July 2009, he announced his withdrawal from shot putting, saying that while he had a dream of competing at the 2012 Summer Olympics, his physical condition would not allow it.

The same year, he backed Nicolai Wammen, from the Social Democrats, in Aarhus' municipal elections.
