Lists of twin towns and sister cities

This is a list of "twin towns" or "sister cities" — that is, pairs of towns or cities in different countries which have town twinning arrangements. Where known, the date of formation of the twinning agreement is included in parentheses.

Note that the list is likely to always remain incomplete, since no canonical list of such arrangements exists; even those towns that are listed may well have arrangements which are not listed here. Note also that any twinning arrangement should be listed at two locations in the list: once for each of the towns involved in the arrangement.

Due to the extreme size of this list and for ease of navigation, the list is divided into several separate lists by continent, which are then organized by country, and in some cases (where there are a large number of twinnings to list) by an appropriate sub-division of the country (e.g. England is divided by ceremonial county). Lists for some countries have in turn been moved to separate lists, which are linked individually below.
