Moravian dialects are the varieties of Czech spoken in Moravia, a historical region in the east of the Czech Republic. There are more forms of the Czech language used in Moravia than in the rest of the Czech Republic. The main four groups of dialects are the Bohemian-Moravian group, the Central Moravian group, the Eastern Moravian group and the Lach (Silesian) group. While the forms are generally viewed as regional variants of Czech, some Moravians claim them to be one separate Moravian language.

Moravians are a West Slavic ethnographic group from the Moravia region of the Czech Republic, who speak the Moravian dialects of Czech or Common Czech or a mixed form of both. Along with the Silesians of the Czech Republic, a part of the population to identify ethnically as Moravian has registered in Czech censuses since 1991. The figure has fluctuated and in the 2011 census, 6.01% of the Czech population declared Moravian as their ethnicity. Smaller pockets of people declaring Moravian ethnicity are also native to neighboring Slovakia.
