Beira (European Portuguese pronunciation: [ˈbɐjɾɐ]) was one of the six traditional provinces or comarcas of Portugal.
The most important cities within the borders of the traditional province are: Coimbra, Aveiro, Leiria, Viseu, Castelo Branco, Guarda, Figueira da Foz, Covilhã and Pinhel.
The largest mountain range is Serra da Estrela – Continental Portugal's highest – other ranges being the Caramulo, Marofa, Gardunha, and Bussaco.
After the 15th Century, the new Kingdom of Portugal was divided into six great administrative units, referred to as comarcas.
Oeste Subregion, part of Estremadura, is the major exception.
