Edward Joseph Giroux (July 4, 1883 – May 26, 1930) was a Canadian professional ice hockey player best known for being the only 20-year-old to have competed in the 1904 Stanley Cup Playoffs.

He first appeared in the Stanley Cup playoffs in February 1904, at the age of 20, while playing for the OHA senior champion Toronto Marlboros.

A Toronto Star story on September 13, 1904, notes that Giroux had taken up residence in Rat Portage (later Kenora), Ontario the hometown of his Marlboros teammate Tommy Phillips who had returned home that May.

Giroux was in net when Kenora defeated Brandon on March 16 and 18, to win the Manitoba Championship and retained the Stanley Cup.

When Kenora challenged the Winnipeg Victorias for the Allan Cup in March 1911, Giroux officiated along with long-time friend Tommy Phillips.
