Ethan Byron "Chopper" Moreau (born September 22, 1975 in Huntsville, Ontario) is a professional ice hockey left wing and team captain of the Edmonton Oilers of the National Hockey League. He was selected in the first round of the 1994 NHL Entry Draft, 14th overall, by the Chicago Blackhawks.

When Moreau was selected by the Blackhawks, he had just completed his third year in the OHL, playing for Niagara Falls. In addition to good physical presence and skating, Moreau had shown a remarkable scoring touch in his draft year. The Blackhawks allowed Moreau to play another year in junior (for Sudbury), before bringing him to their IHL team in Indianapolis. Moreau also saw spot duty in the NHL, playing 8 games.

The following season was Moreau's first full year in the NHL, and he went on to play parts of four seasons with the Hawks. Then, March 20, 1999, Moreau was dealt in a blockbuster trade to the Edmonton Oilers along with Chad Kilger, Daniel Cleary and Christian Laflamme in exchange for Boris Mironov, Dean McAmmond and Jonas Elofsson.
