thumb|The [[Greater São Paulo|São Paulo metropolitan area is the most populous metropolitan area in the Americas, with a population of 23,443,587 as of 2022.]]
This list of largest metropolitan areas in the Americas has the top 50 most populous as of the most recent census results or projections. It is impossible to definitively compare and rank areas, because each country may set its own definition of metropolitan area. Where available, it uses official definitions of metropolitan areas based on one urban core and immediate surroundings, as opposed to polycentric conurbations. Population data are the most recent census results or projections from the authoritative national agency responsible for demographics.
