What is the highest capital city in the world?

La Paz, Bolivia, is often mentioned as the highest administrative capital in the world, set up at about 3,640 metres (11,942 feet). Quito, Ecuador, is generally named the highest constitutional capital, so it gets referenced in a slightly different way.

Bolivia runs with this unusual dual-capital setup. The official constitutional capital is Sucre at around 2,810 metres, yet La Paz acts as the working centre where the executive and also the legislative branches operate from. Because the altitude is so extreme, travellers who arrive straight into La Paz by plane are exposed to the serious danger of acute mountain sickness, and they should get acclimatisation started immediately, even before making plans.
