Liptó County (Hungarian: Liptó vármegye, Latin: Comitatus Liptoviensis, Slovak: Liptovská župa, German: Komitat Liptau, Polish: Komitat Liptów) was an administrative county (comitatus) of the Kingdom of Hungary.

Three villages (Liptovská Teplička, Štrba and Štrbské Pleso) are now in the Poprad District.

Liptó county as a Hungarian comitatus arose before the 15th century.

At various points throughout history the county was ruled by Voivodes or Counts from the Rosenberg, Csák and Benyovszky families.

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