Trevor Marsicano (born April 5, 1989) is an American speed skater and silver medalist in the Winter Olympics.

Marsicano's breakthrough performance was at the 2009 World Single Distance Championships where he won four medals (one gold, one silver, two bronze).

Marsicano started playing ice hockey, but switched to short track speed skating at a young age with the Saratoga Winter Club.

At the 2009 World Allround Championships, Marsicano finished 5th, only being beaten by Sven Kramer, Håvard Bøkko, Enrico Fabris and Wouter olde Heuvel.

On March 7, 2009, at the Salt Lake City Olympic Oval, he became the first skater to break the 1:07 barrier in the 1000 m, clocking 1:06.88 for the distance, 12/100 better than Pekka Koskela's world record of 1:07.00.

Kuck, Hedrick and Marsicano eliminated Japan in the quarterfinal, which advanced them to face the heavily favored Netherlands in the semifinal.

The same trio that skated the semifinal trailed Canada in the gold medal final by as much as 0.73 seconds early in the race, trimming that margin to 0.21 at the finish with a time of 3:41.58.
