The Party of National Unity (Czech: Strana národní jednoty or Strana národního sjednocení) was a party created on 21 November 1938 in the Czech part of Czechoslovakia after the occupation of large parts of the country by Germany (Munich Agreement) and Hungary (First Vienna Award) as a last attempt to unify forces to save Czechoslovakia from disappearing.

The latter two founded the National Labor Party in December 1938 as a non-Communist left "loyal opposition".

Its chairman was the nation's Prime Minister, Rudolf Beran.

The party was forcibly dissolved after the creation of the Protectorate of Bohemia and Moravia in March 1939.

Some of the membership created the Národní souručenství (National Partnership), the only Czech political organization permitted by the Germans in the Protectorate.
