Marco Antonio Arriagada Quinchel (born October 30, 1975, in Curicó) is a Chilean professional racing cyclist. He is the brother of cyclist Marcelo Arriagada. He carried the flag for his native country at the opening ceremony of the 2007 Pan American Games in Rio de Janeiro, Brazil.

He later received a four-year ban.
