Frederick Roy Millar MBE is the Irish Football Association's director of coaching and former head coach of the Northern Ireland national under-21 football team. Born in Belfast, he previously played in the Irish League for Cliftonville F.C. and with Dundela F.C. in the old 'B' Division. Since joining the Irish FA as a coach in 1982 Millar has at some point taken charge of all youth teams from Under-16 to Under-19 and also the Northern Ireland B team and the Northern Ireland Elite (Under-19) squad that takes part in the Milk Cup.
On 29 April 2008 the Irish FA announced a restructuring of their coaching framework with Millar stepping down from his role as Northern Ireland Under-21 coach. At the same time Mal Donaghy and Kenny Shiels also left their positions as Under-19 and Under-17 teams respectively. Millar retained his position as Director of Coaching through to 2009.
An investigation revealed that, in 2007 and 2008, Millar had accepted payments from unwitting candidates for worthless Irish FA coaching certificates.
