Relatives said 18-year-old freshman Stevens Glemaud of West Orange, New Jersey had been missing for more than two days.
They say he disappeared from campus just hours before they came to help him move back home for the summer.
Drexel officials say Glemaud was last seen leaving his west Philadelphia dorm early Saturday. Police said there were no signs of foul play.
A police spokeswoman said Monday night that a body recovered from the river that afternoon near the Philadelphia Museum of Art had been identified as that of Glemaud. She said the death is being treated as a drowning.
Drexel is a private university in Philadelphia serving about 23,500 students.
