Fakhar Zaman hit a spectacular century to propel Pakistan to 338-4 in the scorching south London sunshine.
Mohammad Amir then tore through the India top order to help reduce the defending champions to 54-5.
India eventually limped to 158, Pakistan winning by 180 runs to take their first global 50-over title since 1992.
That Pakistan lifted the title was surprising enough - at eighth in the world they began as the lowest-ranked team in the tournament - but it is the way they demolished the strong favourites will live long in the memory.
Firstly Fakhar flayed the ball all around the The Oval, a maiden century coming in his fourth ODI after Pakistan were invited to bat.
And then Amir, in the same city in which he committed the spot-fixing offences that led to a five-year ban, found precious movement to destroy the vaunted India batting line-up.
The rest of the Pakistan attack were irresistible, backed up by excellent fielding, all in front of a vibrant, raucous and enthusiastic capacity crowd.
