The Estelada (Eastern Calatan: [əstəˈlaðə]; pl. Estelades; full name Senyera estelada, lit. 'starred flag' or 'lone star flag', from estel, "star") is a flag flown by Catalan independence supporters to express their support for an independent Catalonia or independent Països Catalans (Catalan Countries, the Catalan-speaking territory, which includes Valencia and the Balearic Islands). The design of the Estelada comprises the red-and-yellow bars of the Senyera, with the addition of a five-pointed star in a triangle at the hoist.
The use of this flag as a protest symbol within Catalan nationalism has become more notable since the 1970s Spanish transition to democracy. The self-proclaimed Catalan Republic of 2017 did not adopt the Estelada as its national flag, instead using the regular Senyera.
