Valentín Demetrio Paniagua Corazao (23 September 1936 – 16 October 2006) was a Peruvian lawyer and politician who briefly served as President of Peru from 2000 to 2001. Elected President of Congress on 16 November 2000, he ascended to the presidency as incumbent Alberto Fujimori and both his Vice Presidents resigned by 22 November 2000.
