The Central Junior League (Polish language: Centralna Liga Juniorów, CLJ) is a Polish youth football competition. Created in mid-2013, it replaced Mloda Ekstraklasa as the highest level of youth football in Poland. Initially serving as the top tier for under-19 teams (replaced by under-18 teams from 2017 to 2022), it has since introduced under-17 and under-15 divisions. The winners of each level are crowned junior champions of Poland in their age group, with the under-19 champions advancing to the UEFA Youth League.
First tournament of Polish U-19 championship took place in the summer of 1936, see Football Junior Championships of Poland. The formula of the U-19 games changed several times. In some years, there was a final match, taking place before an international game featuring the national team of Poland, while on other occasions, there was a final tournament, featuring four top U-19 teams, winners of local competitions. At regional level, the championships were organized by local branches of Polish Football Association (PZPN).
