María Eva Duarte de Perón (7 May 1919 – 26 July 1952) was the second wife of Argentine President Juan Perón (1895–1974) and served as the First Lady of Argentina from 1946 until her death in 1952. She is usually referred to as Eva Perón (Spanish: [ˈeβa peˈɾon]), or by the affectionate Spanish language diminutive Evita.

In 1951, Eva Perón announced her candidacy for the Peronist nomination for the office of Vice President of Argentina, receiving great support from the Peronist political base, low-income and working-class Argentines who were referred to as descamisados or "shirtless ones". However, opposition from the nation's military and bourgeoisie, coupled with her declining health, ultimately forced her to withdraw her candidacy.

In 1952, shortly before her death from cancer at 33, Eva Perón was given the title of "Spiritual Leader of the Nation" by the Argentine Congress. Eva Perón was given a state funeral upon her death, a prerogative generally reserved for heads of state.

Eva Perón has become a part of international popular culture,most famously as the subject of the musical Evita (1976)
