This is a list of places in Luxembourg 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 comprises villages, cities, districts, counties, etc. with similar links.
Niederanven is a founding member of the Douzelage, a town twinning association of 23 towns across the European Union. This active town twinning began in 1991 and there are regular events, such as a produce market from each of the other countries and festivals.
