Piet Rooijakkers (born August 16, 1980 in Gerwen, North Brabant) is a road bicycle racer from the Netherlands.

[1] After Rooijakkers finished his Bachelor's degree in business in 2002, he decided to find a part-time job so he would have enough time for cycling.

He returned for the 2004 season and won the Criterium of Lieshout and finished third in the Dutch National Amateur Road Race Championships ('vrije renners').

He delivered a very strong performance in the Ster Elektrotour, which gained him the interest of the Axa Pro Cycling Team, who, in 2005, signed him as a semi-professional.

Rooijakkers started in the 2009 Tour de France, where he fell during the 4th stage (a team time trial).
