The Slavic peoples are an Indo-European panethnicity living in Central Europe, Eastern Europe, Southeast Europe, North Asia and Central Asia. The term Slavic represents a broad ethno-linguistic group of people, who speak languages belonging to the Slavic language family and share, to varying degrees, certain cultural traits and historical backgrounds. From the early 6th century they spread to inhabit most of Central and Eastern Europe and the Balkans. In addition to their main population centre in Europe, some East Slavs (Russians) also settled later in Siberia and Central Asia. Part of all Slavic ethnicities emigrated to other parts of the world. Over half of Europe's territory is inhabited by Slavic-speaking communities. The worldwide population of people of Slavic descent is close to 400 million for which they rank fourth among panethnicities in the world.

Modern nations and ethnic groups called by the ethnonym Slavs are considerably diverse both in appearance and culturally, and relations between them – even within the individual ethnic groups themselves – are varied, ranging from a sense of connection to feelings of mutual hostility.
