One of the earliest recorded instances of the name Eguiluz can be found in the Cartulario de San Millán de la Cogolla, a 10th-century cartulary from the Monastery of San Millán de la Cogolla in La Rioja, Spain.

Notable individuals include Juan Eguiluz, a prominent landowner and military leader who fought in the Reconquista against the Moors in the 12th century, and María Eguiluz, a respected scholar and author of religious texts in the 15th century.
