All seven candidates sat down with BBC Radio Manchester's Michelle Dignan to discuss their priorities and policies.
You can listen to a round-up of their chats below or hear each of the individual interviews by going here.
Seven candidates are taking part in the election on Thursday 30 July.
People living in all 10 boroughs of Greater Manchester will be able to vote.
Here is the list (in alphabetical order, by surname) of all seven candidates.
The role of mayor was created as part of a law passed in 2016, one of a number of big pieces of devolution legislation brought in by the Conservatives after taking power in 2010.
In a 2012 referendum, Manchester rejected having a directly elected city mayor, along with eight other major cities, but the decision to have a regional or metropolitan mayor was directly negotiated between the government and the 10 Greater Manchester councils.
Andy Burnham, who left Parliament to stand for the role, was chosen as Labour's candidate for the first mayoral election in 2017 and won, taking 63.4% of the vote.
He went on to fight and win two more mayoral election contests - in 2021 and 2024. He increased his vote to 67.3% in 2021, and polled 63.4% in 2024.
This election - technically a by-election - was triggered by the resignation of Andy Burnham after he was successful in the Makerfield by-election last month.
Greater Manchester's mayor cannot be an MP. This meant that Burnham, who has of course since become prime minister, had to stand down.
Burnham became the city region's first directly elected mayor in 2017 and went on to secure two further terms in office.
