Littler once again played like a different star in the final - and averaged around 115 at times.
The Englishman broke Wright's first throw and eventually led 5-2, but "The Nuke" collapsed and completely lost his way.
Wright secured the re-break and break to make it 6-5 and then again to make it 8-5 - six legs in a row for the Scot.
To the match centre: Peter Wright v Luke Littler
It's a huge relief for Wright after an extremely poor 2024.
He hasn't made it past the third round on the European Tour this calendar year, and has managed a meagre two wins in 16 weeks of Premier League.
His last tournament victory dates back to October 2023, when he won the European Championship.
Wright's path to the final began on Friday evening with a win over Niko Springer (6-4), before defeating Stephen Bunting (6-5), Gian van Veen (6-4), Michael van Gerwen (6-4) and Dave Chisnall (7-5).
