In the history of Czechoslovakia, normalization (Czech: normalizace, Slovak: normalizácia) is a name commonly given to the period 1969–87.
It was characterized by initial restoration of the conditions prevailing before the reform period led by Alexander Dubček (1963/1967 – 1968), first of all, the firm rule of the Communist Party of Czechoslovakia, and subsequent preservation of this new status quo.

"Normalization" is sometimes used in a narrower sense to refer only to the period 1969 to 1971.

The official ideology of normalization is sometimes called Husakism after the Czechoslovak leader Gustáv Husák.
