José Clemente Paz (2 October 1842 – 10 March 1912) was an Argentine politician, diplomat and journalist, founder of La Prensa.
Paz was born in Buenos Aires and started his education in that city but was forced to move to Rosario due to the civil war fought in Argentina.
Paz saved himself by jumping into the Paraná River and swimming to the Buenos Aires ships, thus returning to the city of his birth.
At the end of the war he decided to enter politics, and worked for the party of Adolfo Alsina and began studies in law.
Paz returned to Argentina to manage the newspaper, and, though he relocated to Monte Carlo in 1900, he commissioned the building of a palace in the Retiro area of Buenos Aires.
