Belarusians (Belarusian: беларусы, biełarusy, Russian: белорусы, byelorusy) are an East Slavic ethnic group who populate the majority of the Republic of Belarus. There are over 8 million people who associate themselves with the Belarusian nationality today.

Belarusians also form minorities in neighboring Poland (especially in the Podlaskie Voivodeship), Russia and Lithuania. At the beginning of 20th century Belarusians constituted a majority in the regions around Smolensk.^{[citation needed]}

Noticeable numbers have emigrated to the United States, Brazil and Canada in the early 20th century. During Soviet times, many Belarusians were deported or migrated to various regions of the USSR, including Siberia, Kazakhstan and Ukraine.

Since the breakup of the USSR several hundred thousand have emigrated to the European Union, United States, Canada and Russia.

The most spoken language in Belarus is Russian, principally spoken by 72% of the population, while the other official language, Belarusian, is only used by 11.9% in every day life. Statistical data shows that Belarusian is fluently communicated, read and written by 29.4%, while 52.5% of the population can communicate and read in Belarusian. Belarusian is a language of the Eastern Slavic group.
