Leoncito Astronomical Complex, Astronomical observatory in El Leoncito National Park, Argentina.
The complex houses multiple advanced telescopes at 2552 meters elevation, including the Jorge Sahade telescope with its 2.15-meter diameter mirror.
The National Scientific and Technical Research Council of Argentina established the observatory in 1983, with formal operations beginning in September 1986.
