Turóc (Hungarian, historically also spelled Túrócz), Slovak: Turiec, Latin: Thurotzium/comitatus Thurociensis, German: Turz) was an administrative county (comitatus) of the Kingdom of Hungary.

Turóc county shared borders with the counties of Nyitra, Trencsén, Árva, Liptó, Zólyom and Bars, situated between the Lesser Fatra (Kis-Fátra) and Greater Fatra (Nagy-Fátra) Mountains.

The capitals of the Turóc county were the Szklabinya Castle and Turócszentmárton (present-day Martin; Slovak name until 1950: Turčiansky Svätý Martin); from 1772 only Turócszentmárton was the capital.

Turóc county as a Hungarian comitatus arose in the 14th century.

In the aftermath of World War I, the area of the now defunct Turóc county became part of newly formed Czechoslovakia, as recognized by the concerned states in 1920 by the Treaty of Trianon.
