U20 champions Celtic completed their Development League fixtures unbeaten with a 2-1 win over Motherwell on Friday.
Tommy McIntyre's side, who clinched the title in early April, won 28 and drew four of their 32 matches, scoring 71 goals and conceding just 15.
Hamilton Accies were second in the table, with last season's winners Aberdeen in third place and St Johnstone fourth.
Celtic will be presented with the U20 trophy at Sunday's first-team game against Aberdeen at Celtic Park, which is live on Sky Sports with a 12.30pm kick-off.
