For Celtic, they must now dust themselves down and prepare for Wednesday, when the Premiership leaders travel to Pittodrie looking to prevent Aberdeen narrowing the gap at the top to three points.
The holders out after an enthralling and action-packed afternoon at Hampden. The day belongs to Ross County.
Their journey from Highland League football now takes them to their second major final and their first in the Scottish League Cup.
Can Hibs deny them on 13 March back at the national stadium?
Some Celtic fans already calling for the sacking of manager Ronny Deila. He had asked to be judged at the end of the season after their exits from both the Champions League and Europa League.
A domestic treble was reckoned to the be just enough to keep the Norwegian his job. Will he be given time to do the double and, even if he does, will he still be at Celtic Park next season? Interesting times ahead.
John, Linlithgow: "The team is rank, the manager is rank, worse team I have seen playing in Celtic jerseys. Peter Lawwell what now...back to the biscuit tin."
John Heron: "Taxi for Deila. Enough is enough."
Alex, Greenock: "For Nigeria, Efe Ambrose plays right midfield and he's great. Why do we insist on playing him in defence?"
"I think we started very well and the first 15 minutes was fantastic football.
"Then the red card comes and it changes the game, but we controlled the game after that.
"Then in the second half it is a clear free kick on Craig Gordon. He was pushed out the way and that shouldn't have been a goal.
"A lot of things went against us and you get punished with easy mistakes.
"We are very disappointed, but I think people will see that we were very good at the start of the game.
"We need to go on and we have three days to bounce back and win against Aberdeen."
BBC Sport Scotland
Hibs manager Alan Stubbs trying manfully to keep the smile from his face. This, of course, means that his on-loan Celtic players Anthony Stokes and Liam Henderson can play in the final. Celebrations all the way from Leith to Dingwall
We have two teams in the final who will give us a good, open game of football.
It will be mixed emotions for Celtic duo Liam Henderson and Anthony Stokes. They are on loan with Hibs and, if their parent club had won today, manager Ronny Deila had made it clear he would not allow them to play in the final.
Now they are clear to face Ross County. Happy?
Janet Martin "That was justice that penalty save it came off head on to his hand." The pundits in the BBC studio seem to agree with that assessment.
Mick Martin "We Just aint good enough under Ronny to do treble. Scottish fitba has been in decline since we had to qualify for the Champions League. Champions should be in automatic."
Bryan Allan "What weird week it will be for Ross County. Upsetting the odd today and giant-killed by Linlithgow Rose next week!" Yes, it is the junior side next in the Scottish Cup for County.
Anonymous: "Stupid comments about no-one wanting this final, so should we just let Celtic or Rangers straight into finals? Ross County won fair and square, get over it, and it's comments like that that do the most harm to the game."
Anonymous: "A final without the Old Firm gives it some interest. Hibs will be taking 30,000+ without doubt."
"I couldn't have dreamt of it any better.
"We still have a long way to go to win it, but it will be a great day.
"We probably deserved it in the end and it means a lot to us, hence the celebrations at the end.
"I went to Aberdeen knowing this club would still go forward without me and I am delighted to back and looking forward."
BBC Sport Scotland at Hampden
Incredible achievement by Ross County. This time last year, they were bottom of the Premiership. Now look at them. Celtic's treble dream is dead. As grim a day for Ronny Deila as it is joyous for Jim McIntyre and his players
"It's a fantastic achievement for the club and I am really pleased for the chairman as he has done so much for the club down the years.
"We were determined to give him a second trip to a national final.
"We thought the way it started it was going to be a long afternoon for us.
"We set up to be stiff and that was anything but stiff.
"We had to hang in and it was a matter of bottle. You saw what Celtic did to Hamilton a few weeks ago after an early goal.
"We had a bit of luck and getting the penalty got us back into it.
"But Celtic are a great team and Scott Fox made some incredible saves.
"It should be a great day in the final."
Anonymous: "If the Celtic manager cant see that Efe Ambrose has been an accident in progress for the past two years then he should not be the manager. It was the Celtic fans who were cheering when Ambrose was sent off, that say's everything about the manager."
Anonymous: "Hate to say it, it will be a sponsors and TV nightmare. Who wants to watch Hibs v Ross County? They won't sell TV highlights to any other country, so once again no harm to Hibs or Ross County, but Scottish football will lose again."
"I think the boys deserved it in the end.
"We stuck to our game plan despite losing an early goal and we won it in the end.
"We came down here with the belief that we can do it.
"It is massive, especially for the fans who made it down here despite the weather deserve it."

Ross County are through to the Scottish League Cup final for the first time, knocking out the holders in the process.
There's pushing and shoving between Leigh Griffiths and Paul Quinn after a terrible lunging challenge from Stefan Johansen on Liam Boyce. In the melee that follows Johansen escapes with a yellow card and Ricky Forster and Quinn also go in the book.
It has been an incredible turnaround for County. The way they defended and the way Celtic started, they could have been blown away. But Celtic have contributed to their own downfall thanks to Efe Ambrose - a player of his experience getting himself sent off in that way
Goalkeeper Scott Fox is all over the place at the resulting corner, but County scramble it clear for a corner.
Scott Fox somehow manages to deflect Leigh Griffiths low drive over the crossbar. It had taken a deflection on the way and the goalkeeper was going in the wrong direction. Great reactions.
Celtic have four minutes plus stoppage time to prevent their hopes of treble and retaining the Scottish League Cup being washed away by Ross County in the Hampden downpour.

Anonymous: "Surprised at no mention of Stefan Johansen blatantly digging heel into penalty spot when Efe Ambrose was sent off. Poor sportsmanship to say the least."
It is 10-man Celtic doing all the pressing now.
Mikael Lustig is given too much space by the County defence at a Gary Mackay-Steven corner, but the Sweden defender fails to find the target with his header from 14 yards.
