There are 11 cities in this list, minus Brunei’s capital city. Originally, I intended to curate just only capital cities in south-east Asia (SEA) nations; however, a few countries such as Myanmar’s, Vietnam’s, and Indonesia’s secondary cities have greater populations than their capital city. Jakarta stands as Indonesia’s capital at the moment until the planned inauguration of their new capital city on 17 August 2024.
Cities below are sorted by size, smallest to largest. The size of those cities is set by administrative boundaries; it does not express the land cover and city sprawl.
