Donovan Jamelle Warren (born January 31, 1989) is an American football cornerback for the New York Jets who signed with them as an undrafted free agent after the 2010 NFL Draft. He attended the University of Michigan through his junior year. Warren is represented by Drew Rosenhaus and his godfather is Jets assistant coach Mark Carrier (Mark Carrier (safety)). There is speculation that with the Jets depth at cornerback, Warren may be converted to safety (safety (American football position)).

During his three years playing for the Michigan Wolverines football team, he started in 34 of 36 games. As a member of the 2009 Michigan Wolverines football team, whom he led in interceptions, he earned 2009 first team All-Big Ten (2009 Big Ten Conference football season) recognition from the media and second team recognition from the coaches. He had chosen Michigan over his hometown favorite University of Southern California because he believed that he would be able to play immediately there. Warren had played high school football at Long Beach Polytechnic High School in California.
