This chapter focuses on Flemish youth work and the most important development and trends. 

Youth work in Flanders is defined by decree as "the social-cultural work based on non-commercial objectives for and by young people between three and thirty years old, organised during leisure time, under educational guidance and to promote the general and integral development of youth, who participate in it on a voluntary basis."

The abovementioned definition applies to formal and non-formal youth work as both types of youth work are run by organisations with non-commercial purposes. Generally speaking, there are two sectors in Flemish youth work: universal youth work provision and targeted youth work provision.
