List of divided cities

A divided city is one which, as a consequence of political changes or border shifts, currently constitutes (or once constituted) two separate entities, or an urban area with a border running through it. Listed below are the localities and the state they belonged to at the time of division.

Especially notable examples of divided cities are divided capitals, including Nicosia (since 1974, ongoing), Jerusalem (1948–1967 ''de jure''; ongoing since 1948), and Berlin (1949–1990).
