Popular Union () is a centre-right political party in Argentina rooted in Peronism. Established by Juan Atilio Bramuglia as both a contingency for Peronists displaced by the 1955 military coup against the populist President Juan Perón, it became a "neo-Peronist" alternative to the exiled leader's line, and subsequently, an alternative to the successive dominant factions in the Justicialist Party.
