The Yugoslavia national under-21 football team existed in the Socialist Federal Republic of Yugoslavia. After the state's dissolution in 1992, the following teams were formed:
- Bosnia and Herzegovina national under-21 football team
- Croatia national under-21 football team
- North Macedonia national under-21 football team
- Kosovo national under-21 football team
- Slovenia national under-21 football team
- FR Yugoslavia national under-21 football team
- Serbia national under-21 football team
- Montenegro national under-21 football team
Following the realignment of UEFA's youth competitions in 1976, Yugoslavia's Under-21 team was formed. The team had a varied record, reaching the last four in four tournaments and failing to qualify for four. Yugoslavia won the inaugural competition in 1978. Since the under-21 competition rules insist that players must be 21 or under at the start of a two-year competition, technically it is an U-23 competition. Yugoslavia's record in U-23 competitions is also shown.
