Celtic claimed the cinch Premiership title with a 1-1 draw against Dundee United at Tannadice as they made it 31 league games without defeat.
Giorgos Giakoumakis headed the Hoops in front but Dylan Levitt equalised to secure European football for Tam Courts' side.
Motherwell will also be playing in Europe next season after beating Hearts 2-1 at Fir Park while Rangers saw off Ross County 4-1 at Ibrox.
In the bottom six, St Johnstone defeated Aberdeen 1-0 at McDiarmid Park, meaning Dundee have been relegated to the cinch Championship. St Mirren and Livingston drew 0-0 in Paisley.
Neil Doncaster, SPFL chief executive, said: “I would like to warmly congratulate Celtic’s players, management team and directors on winning the cinch Premiership.
“Celtic have now gone a very impressive 31 matches without defeat in the cinch Premiership and deserve real credit for how well they have performed in recent months.
“They are worthy champions and now have the added bonus of winning direct entry to the group stages of next season’s UEFA Champions League.
“It has been a compelling season in the cinch Premiership, made all the better by the fact that supporters have been allowed back in stadiums in large numbers again, and we wish all clubs the best of luck in this weekend’s final fixtures.”
