The 1973–74 Marquette Warriors men's basketball team represented Marquette University in NCAA Division I men's competition in the 1973–74 academic year.
At that time, Marquette was an independent school not aligned with any conference; it did not join a conference until 1988, when it joined the Midwestern Collegiate Conference, now known as the Horizon League; it would later move to the Great Midwest Conference and Conference USA before joining its current conference, the Big East, in 2005. Also, Marquette did not adopt its current nickname of "Golden Eagles" until 1994.
