Herminio Iglesias (20 October 1929 – 16 February 2007) was an Argentine politician and trade unionist.

Henceforward a supporter of the Peronist Party, Iglesias was elected as the Mayor of Avellaneda in the Province of Buenos Aires upon Juan Domingo Perón's 1973 return from exile and subsequent election to his final turn at the Argentine Presidency.

Aligning himself with Perón's most right-wing adviser, José López Rega, during the internal strife that followed Perón's 1974 passing, he was dismissed from this post following the 1976 military coup headed by General Jorge Videla.

At a "victory rally" towards the end of the election campaign, his followers approached him with a cardboard coffin with the inscription "UCR" (representing their main opposition), which he set on fire.

[1] For many observers,[2] this act was perceived by public opinion as a recall of the country's recent violent past, and was decisive in the victory of the UCR in the general elections and in his own loss to UCR gubernatorial candidate Alejandro Armendáriz.
