Moussa Dembele scored the winner with three minutes remaining to send Celtic through to the League Cup final.
Celtic were on top in the first-half as Rangers set-up to neutralise their attack and resulted in them offering very little in attack.
Scott Sinclair had the best chance 15 minutes into the game after linking up well with Moussa Dembele, but the ‘keeper matched his shot with a good save.
Tom Rogic had a great chance in the fist-half after pressing high up the field and intercepting a poor touch from Gilks but couldn’t steady himself and connect with the ball cleanly.
Three minutes into the second-half Erik Sviatchenko headed the ball into the net but Craig Thomson gave a free-kick against the defender.
Dembele had a huge chance after and chested the through ball down but scuffed his volleyed attempt on goal.
Rangers had chances of their own but held on for much of the second half as Gilks put in a terrific performance between the posts.
Leigh Griffiths came off the bench and played a super ball to Dembele for his 14th goal of the season.
