Líneas Aéreas Privadas Argentinas (English: Private Argentine Air Lines), more commonly known by the acronym LAPA, was an airline based in Buenos Aires, Argentina. At its heyday, the carrier operated international services to the United States and Uruguay, as well as an extensive domestic network within Argentina. Additionally, the company also operated charter services. Domestic and regional flights were operated from downtown's Aeroparque Jorge Newbery, whereas an international service to Atlanta was operated from Ministro Pistarini International Airport. LAPA was the first carrier to break a monopolistic market controlled by Aerolíneas Argentinas and its sister company Austral Líneas Aéreas, offering competitive prices. It ceased operations in April 2003.

The airline was formed in 1977, initially aimed at providing internal services within the Buenos Aires Province. In May 1978, it was authorised to operate charter services to cities in the Americas, and scheduled services began the following year. By July 1980 (1980-07), the major shareholder of the company was Claudio Zichy-Thyssen; the fleet comprised three YS-11As and a Piper Cheyenne that worked on a domestic passenger and cargo network serving Concordia, Ezeiza Airport, Gualeguaychu, La Plata, Necochea, Olavarria, Parana, Pehuajo, San Nicolas and Tres Arroyos. Gustavo Deutsch acquired the company in 1984, when it had a network consisting of two domestic routes served with a single propeller aircraft.
