Celtic made it four wins on the bounce after coming back from a second-half deficit to take all three points at McDiarmid Park.
Neil Lennon’s men found themselves in a hole when Shaun Rooney rose above Greg Taylor and Callum McGregor to power a header past Scott Bain shortly after the restart.
Odsonne Edouard took his scoring streak to six consecutive games with a front-post volley past Zander Clark after being picked out by a Ryan Christie cross.
Christie had a hand in the winner as well, dummying for Taylor to cross into Edouard. The striker netted to take a touch and keep his composure before dispatching into the back of the net.
The recent strong run has all but cemented a place in the top two for Celtic, who are now 12 points ahead of Hibs in third.

Frustrating at times with his use of the ball, though he still managed to get one assist and played a role in the winner as well. Photo: Craig Williamson - SNS Group
