The 1902–03 Harvard Crimson men's ice hockey season was the sixth season of play for the program. The team was led by captain Winsor Soule and played its home games at various locations, including the St. Nicholas Rink in New York City and outdoor surfaces in Cambridge, Massachusetts.
Harvard competed as a member of the Intercollegiate Hockey League (IHL) during this period. The Crimson finished the season with an undefeated record of 7–0–0, capturing the intercollegiate championship. The season was characterized by defensive efficiency, as the team allowed only eight goals across seven games while scoring thirty-one.
In league play, Harvard recorded victories over Brown (7–0), Princeton (4–1), and Columbia (5–1). The season concluded with a two-game series against Yale to determine the league title. Harvard won both contests, defeating Yale 3–0 on February 21, 1903, and 5–1 on February 28, 1903.
At this time in collegiate athletics, the team did not have a formal head coach, a common practice for ice hockey programs of the era. The leadership and tactical direction were primarily provided by the team captain.
