Marcelo Alejandro Horacio Guinle (28 September 1947 – 8 June 2017) was an Argentine politician affiliated with the Justicialist Party. He represented Patagonia's coastal province as a national senator from 2001 through 2015 and held the office of Provisional President of the Argentine Senate between 2003 and 2006. Born in the city of Santa Fe, Guinle later became closely associated with the province of Chubut and the city of Comodoro Rivadavia, where he served as mayor in the 1990s.

Political career and offices

Guinle's public career combined municipal leadership and national legislative work. He was mayor of Comodoro Rivadavia from 1995 to 1999, a city known for its petroleum industry and role as a regional hub in Chubut. He went on to serve in the Argentine Senate from 2001 to 2015. During part of his tenure in the upper chamber, he served as Provisional President of the Senate, an office that presides over the body in the absence of the vice president and figures in the Senate's internal organization and legislative agenda.

Context and responsibilities

As a senator from a Patagonian province, Guinle took part in national debates affecting regional development, energy, infrastructure and local administration—areas commonly important to representatives of southern provinces. His affiliation with the Justicialist Party placed him within Argentina's broad Peronist tradition, which has been one of the country's main political currents since the mid-20th century.

Offices held

Guinle's career illustrates a trajectory common in Argentine politics: movement from municipal government to national legislature while remaining identified with regional concerns. He was regarded as a public figure with long-standing ties to the communities he represented.

Marcelo Guinle died in Comodoro Rivadavia on 8 June 2017 from cancer at the age of 69. His passing was noted in Chubut and national political circles as the loss of a seasoned legislator who had served both local and national offices.
