Biggest Cities by South American Countries

Name the three most populous cities (city proper) in each country listed below. Population is based on municipal boundaries, not metropolitan areas. For the sake of curiosity and information the populations are showed, and althought the capitals aren't always the most populated cities, by intuition they were mostly placed first.

Populations are based on the most recent estimates (≈2024–2025) using city proper data.
