Kálmán Darányi de Pusztaszentgyörgy et Tetétlen (22 March 1886 – 1 November 1939) was a Hungarian politician who served as Prime Minister of Hungary from 1936 to 1938.

His uncle was Ignác Darányi who served as the Minister of Agriculture during the Austro-Hungarian Monarchy.

In addition to his political activities he played a leadership role in the Agricultural class movement.

He maintained the promise of secret suffrage, but first of all he wanted to increase the gubernatorial jurisdiction and the House of Magnates' role.

Darányi and his Minister of Foreign Affairs, Kálmán Kánya attempted to strengthen contacts with the United Kingdom and France to balance pressure from Nazi Germany.

Hungarian foreign policy continued to promote the country's relationship with Italy at the same time.

The Regent was now allowed to delay the implementation of bills by up to a year, and he was no longer accountable to Parliament.

This law modified earlier provisions in two areas: it abolished the open vote in favor of the secret ballot, but narrowed suffrage rights.

Darányi began secret negotiations with Kálmán Hubay with the intention of uniting right extremist forces.

Kálmán Darányi served as Speaker of the House of Representatives from 5 December 1938 until his death.
