Slovakization or Slovakisation is a form of either forced or voluntary cultural assimilation, during which non-Slovak nationals give up their culture and language in favor of the Slovak one. This process has relied most heavily on intimidation and harassment by state authorities. In the past the process has been greatly aided by deprivation of collective rights for minorities and ethnic cleansing, but in the last decades its promotion has been limited to the adoption of anti-minority policies and anti-minority hate speech.

Hungarians constitute the largest minority in Slovakia. According to the 2021 Slovak census, 456,154 people declared themselves Hungarian, while 462,175 stated that Hungarian was their mother tongue.
