Venezolana Internacional de Aviación Sociedad Anónima or VIASA for short, was the Venezuelan flag carrier between 1960 and 1997. It was headquartered in the Torre Viasa in Caracas. Launched in 1960, it was nationalised in 1975 due to financial problems, and re-privatised in 1991, with the major stake going to Iberia. The company ceased operations in January 1997, and went into liquidation.

Viasa was envisioned by the government of Venezuela in 1959 to create a new company that could serve as the country's flag carrier and run without government intervention. It was set up in 1960 when the international routes operated by Línea Aeropostal Venezolana (LAV) and Avensa were merged and taken over by the newly created carrier. The government contributed 55% of the capital, while private investors (among which were LAV and Avensa, the latter owned by Grupo Boulton and Pan American World Airways) contributed with the remainder.
