The animal somehow got trapped in a storm drain in Browns Mills earlier this month.
The baby deer was calling for its mother when a woman happened by and called a non-emergency line for help.
The firefighter wrapped the fawn in a blanket before pulling it to safety.
The New Jersey Department of Wildlife said fawns are often left on their own because their legs are not strong enough to keep up with adult deer, even though the mother will come back several times a day to nurse.
