Clotilde de Urioste Velasco (5 February 1857 - 29 October 1933) was the princess of La Glorieta and a philanthropist.

She married the future Prince of La Glorieta, Francisco Argandoña Revilla in 1874.

Together, they were named princes by a papal bull from Pope Leo XIII on December 28, 1898.

She married Francisco Argandoña Revilla, one of the business partners of her younger brother, Atanasio, after Aniceto Arce insisted to the Urioste family that the union be carried out.

During the Chaco War with Paraguay, he left the country and when the conflict was over he returned in October 1932.
