As the first anniversary of the world's worst terrorist atrocity approaches, town hall chiefs are to draw up plans for the tribute to the thousands of people who were killed.
It is not yet known what form the memorial will take, but it could be a sculpture, statue or monument.
It would be erected in one of the city's parks such as Cathedral Gardens, or Piccadilly Gardens providing a "place of quiet reflection".
The plan has been drawn up by town hall opposition chief Simon Ashley.
The Lib Dem councillor said: "There have always been very strong links between New York and Manchester and I think we should reflect that.
"There have been a number of new spaces in the city that have popped up over the past few months and I think the public would welcome an area where there could be some quiet reflection about the events of that terrible day."
The scheme has won cross-party backing in the council.
In a first for the town hall, it has been seconded - without amendments - by leader Richard Leese.
The council meeting will be held on September 11 on the anniversary of the attacks and the motion for the memorial is expected to be passed unanimously.
Coun Leese said: "September 11, 2001, has been written in time and is a date which changed the world.
"It has had a lasting impact on so many people because for the first - and hopefully last - time it happened right there in people's living rooms."
A garden of remembrance has already been planted in London opposite the US embassy. The motion also says military action in Iraq should not take place without a United Nations mandate.
