The Gibraltar national under-21 football team represents Gibraltar in football competitions at under-21 level and is controlled by the Gibraltar Football Association. It is a full member of FIFA and is therefore eligible to enter any FIFA-sanctioned tournaments. Gibraltar applied for full UEFA membership and was accepted by the UEFA Congress in May 2013 and can therefore compete in the UEFA European Under-21 Championship beginning with the 2015 edition of the tournament, although they did not participate until 2017, in qualification for the 2019 UEFA European Under-21 Championship.
