Jaidon Anthony scored his eighth goal of the season on Saturday
Burnley narrowly missed out on the Championship title despite coming from behind to beat Millwall at Turf Moor and ending the season with 100 points.
Jaidon Anthony's second-half goal put the Clarets 2-1 ahead and on course for a trophy lift, but they were denied top spot by Leeds United's stoppage-time winner at relegated Plymouth Argyle.
Josh Brownhill earlier equalised shortly after Mihailo Ivanovic put the visitors ahead inside 11 minutes, and it was Brownhill who sealed victory with his second of the game late on.
Millwall fell just short of a play-off place, finishing eighth, two points behind Bristol City in sixth.
Millwall had a dream start. Ivanovic darted to the front post in front of CJ Egan-Riley to meet George Honeyman's cross after clever hold-up play by Josh Coburn.
But Burnley hit back instantly through Brownhill. He fired home with a low, emphatic finish into the bottom right corner after Ashley Barnes charged down Jake Cooper's clearance.
Brownhill forced George Evans into a strong save with a strike from distance after 25 minutes, as the home side looked to go ahead on a frantic day of drama.
Millwall's Coburn put forward a contender for miss of the season 10 minutes before the break, hitting the post just yards out from an open goal after being found by Tristan Crama's low cross.
Burnley looked to force the issue early into the second half through Hannibal Mejbri's curling strike, which whistled over the bar, and efforts from Anthony and Marcus Edwards, both blocked by Evans.
But it felt as though a second goal was coming, and Anthony was Burnley's driving force. On 65 minutes, he completed the turnaround with a wonderful first touch and finish inside the area.
Ivanovic failed to connect with a header as another gilt-edged chance went begging, before Cooper was denied by James Trafford as Millwall looked to salvage their dwindling Premier League dream.
Scott Parker's home side survived incredible late pressure before getting their third goal, but the day ultimately ended in disappointment having come so close to glory.
Post-match reaction
Burnley manager Scott Parker speaking to BBC Radio Lancashire:
"I'm so proud. We came into today hoping it would go our way, but wanting to win the game and get to 100 points, we did that.
"If you'd have said to me you'd reach 100 points, 33 games unbeaten, 16 goals conceded and you wouldn't win the league I'd have said 'no chance'. We've done remarkably this year.
"Over the past month or so, when we've gone a goal down, the players' reaction is one of needing to get back in it. We were superb today, we had real quality, created numerous chances; on another day it could have been a lot more.
"The challenge goes up a level or two next year. We've got a rock solid foundation and we've proven that this season. We are going to rest, reboot and we'll come into next year with a driving ambition to be as successful as we can."
Millwall manager Alex Neil speaking to BBC Radio London:
"Whenever you're playing the top teams in this division, it is tough. You need to have a game plan; you have to understand you're not going to dominate the ball.
"That wasn't our intention; we tried to get them to risk the ball so we could nick it and try to counter.
"We had opportunities and didn't make the most of them. In a game of this magnitude when Burnley are chasing the league and we're chasing play-offs, you need to take the key moments and we only converted one. That isn't enough.
"Burnley were the better side, I have no problem saying that. But I've been involved in those moments where if you take your chances you can take the points. Unfortunately today wasn't our day."
