Encostas d'Aire is a Portuguese wine region located on the limestone hills extending across the northern end of the wider Lisboa wine region into the southwestern corner of the Beiras region. The region was initially an Indicação de Proveniencia Regulamentada (IPR) region, but in 2005, it was elevated to Denominação de Origem Controlada (DOC) status, and at the same time the Alcobaça IPR was merged into Encostas d'Aire to form a subregion.

The principle grapes of the Encostas d'Aire region include Arinto, Baga, Fernao Pires, Periquita, Tamarez, Tinta Amarela and Vital.
