Igúzquiza (Basque: Iguzkitza) is a town and municipality located in the province and autonomous community of Navarre, northern Spain.

As reported by the Grand Encyclopedia of Navarre: 'This coat of arms was characteristic of the valley of Santesteban de la Solana, and when Arróniz, Villamayor, Barbarin, and Luquin formed independent municipalities, the remaining populations continued to be administratively united and used the arms of the entire valley.'

Igúzquiza is a village located on flat terrain, surrounded by a large oak forest that, in the late 18th century, extended for about a league and a half.

To the north flows the Ega River, and perched above its escarpment stands a stone and brick castle belonging to the Vélaz de Medrano family, who were the lords of the area.

[5] It borders to the north with the district of Metauten and Allín, to the east with Ayegui, to the south with Dicastillo, the Montejurra communal land, and Luquin, and finally, to the west with Villamayor de Monjardín and Abáigar.
