The Lisbon Astronomical Observatory (Portuguese: Observatório Astronómico de Lisboa) is an astronomical observatory located in Tapada da Ajuda, in the civil parish of Alcântara, municipality of Lisbon. Recognized internationally for its quality of work in the field of positional astronomy (since the 19th century), in 1992, it became a dependency of the University of Lisbon (and later, part of the Faculty of Sciences), responsible for scientific and historical research, along with media relations.
