After two safety cars, crashes and the shock retirement of title-challenger Lewis Hamilton, Formula One's youngest double champion finished in front of McLaren's Jenson Button for only his second win of the season.
Championship leader Fernando Alonso was third, claiming his eighth podium of the season in the dramatic night race around the narrow, demanding street circuit through the heart of downtown Singapore.
Force India's Paul di Resta took an impressive fourth and Mercedes' Nico Rosberg was fifth, ahead of Lotus's former world champion Kimi Raikkonen.
Romain Grosjean, Felipe Massa, Daniel Ricciardo and Mark Webber rounded out the top 10 in a race that did not even reach the 61 allotted laps after hitting its two-hour time-limit, meaning it was halted after 59.
With the win, Vettel climbs to second in the standings behind the consistent Alonso, who has a reduced lead of 29 points. Raikkonen lies third and the unlucky Hamilton drops down to fourth.
"This has been one of toughest races of the year, to be honest," said Vettel, last year's winner in Singapore. "There are so many bumps, there's no room for mistakes and it just seems to go on forever... I'm just incredibly happy."
Hamilton made a smooth start from pole accompanied by Williams driver Pastor Maldonado, but a misjudgment on the first corner cost the Venezuelan two places as Vettel and Button sailed through.
Several cars ran wide on the first two corners and Caterham's Vitaly Petrov lost some of his front wing, but an investigation found no cause for punishment.
Ferrari's Massa was the big loser in the early jostling as he dropped to the back after pitting with a puncture. At the front Hamilton and Vettel, swapping fastest laps, were peeling away from Button.
