Celtic will begin their Champions League campaign against Reykjavík.
Neil Lennon's side will kick off their European fixtures later this month.
They were among the seeded sides in today's draw, which took place in Nyon. 34 teams were featured in the draw, with an equal division of seeded and unseeded clubs based on club coefficient rankings.
With the season starting late due to the Covid-19 shutdown, there will only be one leg. The match will be played at Celtic Park.
The tie will take place on August 18 or 19, with extra time and penalties played if necessary.
Celtic beat Sarajevo 5-2 on aggregate at this stage in last season's tournament, going on to win 7-0 on aggregate against Nõmme Kalju before losing 5-4 across the two legs against CFR Cluj in the third round.
Lennon's men went on to finish top of a Europa League group featuring Cluj, Lazio and Rennes, before being knocked out in the round of 32 by FC Copenhagen.
The winning side will progress to the second qualifying round of the Champions League, while the losing team will play in the Europa League second qualifying round.
