The following is a partial list of adjectival forms of place names in English and their demonymic equivalents, which denote the people or the inhabitants of these places.
Many place-name adjectives and many demonyms refer also to various other things, sometimes with and sometimes without one or more additional words. (Sometimes, the use of one or more additional words is optional.) Notable examples are cheeses, cat breeds, dog breeds, and horse breeds. (See List of words derived from toponyms.)
Entries in italics are continental regions (taking as reference the 7 continents model).
Regions tracing their origins (or otherwise referenced) in Greco-Roman antiquity [in cases where ancient regions are extant, this table is limited to cases where the present-day regional names retain their original/ancient form].
