This will be the first ever European meeting between the two sides and the La Liga club's first ever game against a Scottish opponent.
Match preview
Real Betis claimed their first victory of the new La Liga campaign, when they won 2-1 away at Granada on Monday night.
A 66th minute strike from Colombian forward Luis Suarez cancelled out Rodri Sanchez's first-half opener, however a brilliant solo goal in the 89th minute from substitute Sergio Canales ensured the visitors went home with all three points.
Manuel Pellegrini's men are now preparing for their first European campaign since 2018-19, after an impressive sixth-place finish in the Spanish top flight last season.
Betis have only ever lost one of their previous 12 group stage games in the Europa League and they have never conceded more than once in a single group stage match, keeping eight clean sheets in the process.
Joined in Group G by Bayer Leverkusen and Ferencvaros, Los Verdiblancos will fancy their chances of reaching the knockout rounds and will be hoping to kickstart their campaign with a victory in front of their home supporters.
After two successive defeats against AZ Alkmaar and Old Firm rivals Rangers, Celtic bounced back to claim a comfortable 3-0 win at home against Ross County in the Scottish Premiership last weekend.
Summer signing Cameron Carter-Vickers found the net on his debut to break the deadlock just after the hour mark, before Albian Ajeti scored a brace on his first start of the new season, to seal their third league win.
The Hoops have endured a mixed start to the new campaign, though there have been clear signs of improvement in the last month under head coach Ange Postecoglou, who will become the first Australian to manage in the Europa League.
Further improvements are now required in Europe, following a dismal Europa League campaign last season when they finished bottom of their group with four defeats from their six matches, conceding 19 goals in the process.
Celtic travel to Seville on Thursday having never won an away match against Spanish opponents in 18 attempts against seven different teams. They have also lost each of their last six competitive games against La Liga sides by a staggering aggregate score of 19-1.
If the Hoops are to advance from their group - something they have achieved in three of the last four seasons - then they should be looking to target their encounters against Betis to get points on the board.
