The NEC-based show, taking place from 3 – 5 June, is aimed at grass roots football players and coaches.
"Everyone in the professional game owes a great debt to the thousands of coaches who commit so much time and energy at grass roots level," said Coleman.
"This show offers the opportunity for those people to be afforded recognition and an opportunity to meet up with those in the professional game."
Coleman became the youngest Premier League manager when he took over at Fulham, before his stints in Spain and at Coventry City.
"With his television work, he [Coleman] is also an extremely able communicator which will be very important when it comes to his coaching clinics and seminar sessions with us," said event organiser Joanna Burns.
