Ullíbarri-Gamboa (Spanish: [uˈʎiβari ɣamˈboa], Basque: Uribarri Ganboa Basque pronunciation: [uɾiβari ɣamboa]) is a hamlet and concejo located in the municipality of Arratzua-Ubarrundia, in Álava province, Basque Country, Spain.

The hamlet gives its name to the Ullíbarri-Gamboa Reservoir, the largest in the Basque Country, The construction of the dam, between 1947 and 1956, flooded part of the village as well as most of its farmland, forcing many residents to move to nearby Vitoria-Gasteiz.
