The Northern Ireland national under-19 football team also known as Northern Ireland under-19s or Northern Ireland U19s represents Northern Ireland in association football at under-19 level. It is controlled by the Irish Football Association and began under the name of Ireland Youth when the Home Nations first held a round robin of friendly matches in 1948. The same year they entered the first International Youth Tournament, now the UEFA European Under-19 Football Championship. Their best performance was in 1963 when they finished as runner-up. The team evolved into the Northern Ireland under-18 team then the current under-19 team. As well as the UEFA Under-19 Championships the team also enters the annual Milk Cup (currently as an under-20 side). In addition, the team plays regular friendlies, sometimes as an under-20 or under-18 team by agreement of the opposing association.
