Václav Blažek (born April 23, 1959 in Sokolov, Czechoslovakia) is a historical linguist. He is a professor at Masaryk University (Brno, Czech Republic) and also teaches at the University of West Bohemia (Pilsen, Czech Republic).
His major interests include Indo-European languages, Uralic languages, Altaic languages, Afroasiatic (Hamito-Semitic) languages, Nostratic languages, Dené–Caucasian languages, and mathematical linguistics (lexicostatistics and glottochronology).
In his book Numerals Blažek discusses words for numerals in several language families of Eurasia and Africa (Indo-European, Uralic, Altaic, Kartvelian, Egyptian, Berber, Nubian, and Saharan), with briefer discussions of numerals in other languages around the world.
