Sagàs (Catalan pronunciation: [səˈɣas]) is a small town and municipality located in Catalonia, in the comarca of Berguedà.

[4] Although Sagàs has no coat of arms officially recognized by the Generalitat de Catalunya, the town hall traditionally uses a yellow (for heraldic gold) shield bearing a purple saltire cross with a palm of martyrdom, representing Saint Andrew (or, a saltire couped purpure, overall a palm frond, proper).

The parish of La Guàrdia de Sagàs holds its own celebration on the first Sunday in October, and the town hall often organizes a sopar de germanor, or "community supper", on or around October 16, the feast of Saint Gaudericus (Sant Galderic in Catalan), the patron saint of Catalan farmers.

[7] In book XXXIV of Ab Urbe Condita, Livy refers to Segestica, "an important and opulent city"[8] ("Segesticam [...] grauem atque opulentam ciuitatem"),[9] which most likely corresponds to Sagàs.

[8] The importance of this city in ancient times may explain the large number of pre-Latin place names (la Quar, Olvan, Merlès) found in the area directly around Sagàs.
