Slovenians in the neighbouring countries are compatriots who reside as autochthonous Slovenian national communities in the neighbouring countries, in the historic settlement area of the Slovenian nation. In addition to the terms "zamejstvo" and "zamejci" (translated as Slovenian national minorities in the neighbouring countries), the terms Slovenians in the neighbouring countries, Slovenians in the neighbourhood, and the autochthonous Slovenian national communities and/or minorities are equally used. The areas of the neighbouring countries where the autochthonous Slovenian national community resides and the Republic of Slovenia together form the common Slovenian cultural space.

The autochthonous Slovenian national community exists in all four neighbouring countries, but its numbers, situation and status vary significantly from country to country. 

The life of Slovenians in all four neighbouring countries and their activities can be followed on the online portal Slovenci v sosednjih državah.
