The Gulbenkian Orchestra (Portuguese: Orquestra Gulbenkian) is a Portuguese symphony orchestra based in Lisbon. The orchestra primarily gives concerts at the Grande Auditório (Grand Auditorium) of the Gulbenkian Foundation.

The Calouste Gulbenkian Foundation founded the orchestra in 1962 as the Orquestra de Câmara Gulbenkian (Gulbenkian Chamber Orchestra), consisting of 12 musicians. The ensemble subsequently expanded in size and took on its current name in 1971. The orchestra currently has 66 permanent musicians.
