List of sister cities in Europe

This is a list of twin towns and sister cities in the continent of Europe – that is, pairs of local government entities in different countries which have 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.A searchable, interactive list is maintained by Sister Cities International. Such arrangements are listed at both locations in these lists.
