Steven Gerrard's quickly equalised Jake Livermore's deflected opener in the first half but disastrous defending let in David Meyler before Tom Huddlestone's shot was diverted in
Livermore's first Tigersgoal put the home side in front after 20 minutes at the KC Stadium on Sunday but a superb Steven Gerrard free kick, almost 15 years to the day since his Liverpool debut, levelled matters.
But Hull were rewarded for a stirring second-half performance when Meyler reacted quickest to pick up the loose ball and fire in with 19 minutes remaining before Martin Skrtel's own goal settled the result.
The result catapults the hosts into the top half of the table and leaves Liverpool seven points adrift of Premier League leaders Arsenal.

A dreadful display at the back and a less-than-inspiring one up top for Liverpool sees the Reds fall to a well-deserved defeat at the hands of a very confident Hull City side.
The hosts never looked like giving up, even though they went into the game very much the underdogs. Abject defending helped the Tigers’ cause but it was their attacking spirit that created these chances and get their first win in seven league games.
The absence of Daniel Sturridge and, for the most part, Philippe Coutinho were keenly felt, as the visitors never looked like converting any of their few shots on target, while Liverpool remain comfortably behind Arsenal.
The Tigers had lost four of their previous five Premier League games and, despite Liverpool's dominance of possession, it was the home side who created the first chance. A corner was cleared as far as Alex Bruce after 14 minutes and his teasing cross was glanced just wide by Curtis Davies.
And Hull went in front six minutes later when Livermore and Meyler combined for the former to unleash a shot that took a wicked deflection off Skrtel and flew past Simon Mignolet, his first goal for the club since joining on loan from Tottenham.
But the lead was short-lived as Liverpool captain Gerrard produced a sumptuous free kick that he whipped into Allan McGregor's far corner from 25 yards.
Luis Suarez cut a frustrated figure for most of the half and missed a very presentable opportunity in the final minute of the opening period when Raheem Sterling found the Uruguayan on the left but his side-footed effort was tame and straight at McGregor.
Liverpool should have gone in front after 70 minutes when Coutinho's cross found Victor Moses, who met it on the volley but was denied at point-blank range by McGregor.
McGregor's save proved crucial as Hull regained the lead a minute later after the Reds failed to clear and Meyler picked up the loose ball and showed great composure before firing in his first goal of the season.
Suarez whistled a late free kick wide before Hull put the game out of reach with four minutes remaining when Huddlestone's effort was headed into his own net by the unfortunate Skrtel.
