Jorge Altamira (born José Saúl Wermus in 1942), is an Argentine activist and politician leading the Workers' Party (Partido Obrero) in Argentina.

[5] Son of a printing worker active in the Graphist Union, Altamira began participating in the labor movement at an early age, and took part in a number of strikes.

[1] He was among five Workers' Party leaders arrested during the 1989 riots in Argentina on suspicion of incitement; the charges were later dropped.

He pursued a vigorous labor rights agenda during his tenure at the legislature, and proposed a six-hour workday for Buenos Aires Metro employees working underground, a law protecting workers' self-management of bankrupt businesses, a hike in the minimum wage to cover the poverty line in the city (higher than in most of the rest of Argentina), and a universal healthcare coverage law.

[7] He has unsuccessfully run for both a seat in the Argentine Chamber of Deputies, as well as for the Presidency, and is one of the nine members of the Co-ordinating Committee for the Refoundation of the Fourth International.
