Vitéz Károly Bartha de Dálnokfalva (18 June 1884 – 22 November 1964) was a Hungarian military officer and politician, who served as Minister of Defence between 1938 and 1942.

After the fall of the Hungarian Soviet Republic, Bartha joined the National Army led by Miklós Horthy.

Béla Imrédy appointed him as Minister of Defence and Bartha kept his position in the ensuing governments until 1942.

While he was in office, plenty of major events took place: the First and Second Vienna Awards, the occupation of Bácska and Prekmurje, the bombing of Kassa thereafter Hungary entered the Second World War (1941).

After the communist takeover, he was harassed by the police services, so he chose to emigrate to Venezuela, where he worked as a railway constructing engineer.
