Coleman is a former teammate of current Fighting Irish quarterback Malik Zaire at Archbishop Alter.
Coleman is the 11th prep senior-to-be to pledge to Coach Brian Kelly this recruiting cycle.
Notre Dame had been in contact with the 6-foot, 180-pound Coleman since early May and offered a scholarship on the last day of May. He visited campus this week and pledged to the program before leaving town.
Coleman becomes the first cornerback prospect to commit to the Fighting Irish this cycle. On video, Coleman displays quick feet and exceptional hips and change-of-direction skills. He also shows the ability to accelerate with receivers downfield and rarely loses a step in coverage.
Coleman is rated as a three-star prospect and the No. 45 cornerback in the country by Rivals.com, a national Internet recruiting service. He rates as the No. 69 cornerback according to Scout.com.
Notre Dame is expected to bring in close to a half-dozen defensive backs this cycle and is halfway there with Coleman added to safety prospects Nicco Fertitta and Prentice McKinney.
The Fighting Irish's recruiting haul is currently ranked No. 13 by Rivals.com and is highlighted by four-star linebacker Josh Barajas of Andrean High School and four-star wide receiver C.J. Sanders of Tennessee.
