The news, confirmed by the party today, will be worth an estimated £50m to the local economy.
It means Manchester, which hosted the event in 2006 and 2008, will have been the host city every second year for nearly a decade.
That is on top of the Conservative conference being held in Manchester for the first time later this year.
Conference capital
The news cements Manchester's place as Britain's political 'conference capital' despite fierce competition from rivals like Birmingham and Glasgow.
Experts believe private and public-sector conference have been worth around £100m to Greater Manchester over the past three years - while also boosting its international profile.
Labour's decision to hold its week-long conference in Manchester in 2006 marked the first time it had visited the city since 1917 - and saw Tony Blair deliver his last keynote speech as prime minister.
The 2008 event made national headlines as Gordon Brown saw off a potential coup with a passionate address to the conference hall.
Labour had already confirmed it would return in 2010 - and decided today to add Manchester to the calendar for 2012 and 2014.
There was good news for Liverpool, too, which will host the Labour conference for the first time in 2011.
Phil Woolas MP, Labour's minister for the north west, said: "This is fantastic news for both Liverpool and Manchester and we're very proud to have the Labour party conference regularly coming to the north west in the next few years.
"As Manchester has proven, the Labour party conference will generate millions of pounds for the region's economy with thousands of visitors including delegates, ambassadors, journalists, and business people coming to the city."

Ray Collins, the Labour party's general secretary, said: "The annual conference is the highlight of the party's year, a time when party members come together to discuss how to achieve Labour's vision of a fair future for all.
"Labour broke new ground when we held conference in Manchester in 2006 and in 2011 we will be the first party to visit Liverpool. New host cities provide us with the opportunity to broaden potential conference venues and the people that attend."
Politicians, delegates and the media have all praised Manchester during previous conference for the quality of its facilities and traffic links. It has a ready-made 'conference quarter', based around Manchester Central - formerly known as the G-Mex - with the Midland and Radisson hotels less than one minute's walk away.
Police are able to throw up a 'ring of steel' around the conference zone, patrolled by up to 1,000 police each day.

I look forward to the road closures, extra security and fed up police staff stood on long houred cordons. The disruption it causes our city, making people late for work and closing areas off, is brilliant.
What a boost.......................................................not

Also this conference disrupts Manchester city centre and causes chaos for those living in the city and travelling in and out. The Metrolink stops running past G-Mex, roads are sealed off etc. I thought that the government and council were trying to reduce congestion in town yet before, during and just after this conference the city centre is brought to a standstill. It should be held out of town like when they had the G8 at Gleneagles.
I am sure that the bill to council taxpayers ran into millions last time too.

'Police are able to throw up a 'ring of steel' around the conference zone, patrolled by up to 1,000 police each day.' - SOUNDS LIKE A BARGAIN !!

Now, think about it, They are coming to Manchester, bringing Money to the area, Hotels, Guest Houses, bars, clubs and shopping and if you do not believe that, then it is time that you go the same way you think they are going to go in the next election!
I am one for the conference to be here, because It gives me a chance to have my say to those in charge because they give you a chance to talk to them at least, more than you can say for the leaders from Salford or Manchester councils.

13/08/2009 at 06:51 - WELL SAID - YOU CAN BET YOUR BOTTOM DOLLAR THAT THE MPS PLUS 'ALL' THEIR HANGERS ON WILL NOT BE PAYING OUT OF THEIR OWN POCKETS !! SO £50m ?? - MPs EXPENCES MAYBE ?? GOVERNMENT FUNDING ??
I JUST WONDER AT WHAT PRICE TO THE TAX PAYER !! AND MORE TO THE POINT - THE MANCHESTER TAX PAYER. WHY DONT THEY KEEP IT IN LONDON LIKE THEY DO WITH ALL 'A' LISTED 'MAJOR' EVENTS - OR IS THIS BARELY A 'C' RATED EVENT !!

I would suggest they don their hair shirts and head to Dartmoor. There this shower can cause as much congestion as they want....amongst the goats....and in particular the sheep....they love sheep, thats what they think the Labour voters are...sheep, know what? They are right.
Thanks to Brown and Co. the tories are going to win the next election, Baa Baa Baa....

If it was left to some of you people commenting on here the city would just be a scrapheap of failure.
