Gebara (Spanish: Guevara) is a hamlet and concejo in the municipality of Barrundia, Álava, Basque Country, Spain.

Koldo Mitxelena and Joaquín Gorrochategui [es] have suggested that the toponyms Gébala (Γέβαλα) and Gabálaika (Γαβάλαικα) mentioned in Ptolemy's works as cities of the Varduli could correspond to modern Gebara.

[3] Records are mute during the early Middle Ages, with the first mention occurring in a document from the 11th century about the counts of Oñati.

[citation needed] Gebara played an important role during the War of the Bands of the late Middle Ages as the stronghold of the Ladrón de Guevara [es] family.

The Tower-palace of Guevara is located at the foot of the hill, close to the Church of the Assumption.
