Edwin Sydney Picon-Ackong (born November 4, 1940) is a retired Mauritian football referee. He is known for having refereed one match in the 1986 FIFA World Cup in Mexico between Iraq and Paraguay. This match caused controversy as Picon-Ackong blew the whistle for half time a split-second before Iraq striker Ahmed Radhi's header hit the back of the net, and the goal was ruled out.
