This is a list of places in the United Kingdom having standing links to local communities in other countries. In most cases, the association, especially when formalised by local government, is known as "town twinning" (though other terms, such as "partner towns" or "sister cities" are sometimes used instead), and while most of the places included are towns, the list also includes villages, cities, districts, counties, etc. with similar links.
