Lin drilled an astonishing pitch to within a foot for a tap-in birdie as Northern Irish teenager Rory McIlroy found trees and missed a long putt to end a day of high drama.
Lin, from Taipei, seals the biggest victory of his career after three previous triumphs on the regional tour and becomes the first Asian Hong Kong Open winner since Kang Wook Soon in 1998.
"This is my first European Tour win and my feelings cannot be described," said the beaming Lin. "I'm very excited to be Chinese and win the tournament. I've proved that Chinese can do it."
The 34-year-old had missed a six-foot birdie on the last hole of regulation play to go into the play-off with McIlroy, 19, and Italy's Francesco Molinari, with all three locked at 15-under 265.
Lin then looked to have lost his chance when he drove into thick trees on the first play-off hole, the par-four 18th. But he made a miraculous escape to within four feet for birdie.
Molinari missed his long birdie putt to drop out of the play-off but there were no such problems for McIlroy, who lasered his pitch to within two feet to take them back to the 18th tee.
The teenager then found trees but kept his hopes alive with another breathtaking shot to the edge of the green. But he could not hole the putt, making Lin's victory a formality.
"Lin probably should have won it in regulation, and he made two threes in the play-offs. You can't beat that, to be honest," said McIlroy.
Defending champion Miguel Angel Jimenez shot 62 on the final day while Germany's Bernhard Langer ended three off the pace.
