The surname Olavarria has its origins in the Basque region of Spain, tracing back to the medieval period. The name is derived from the Basque words "ola," meaning "mill," and "berri," meaning "new," suggesting a connection to a new mill or a person associated with a newly established mill.

One of the earliest recorded instances of the surname Olavarria can be found in the Cartulario de San Millán de la Cogolla, a collection of medieval documents from the Monastery of San Millán de la Cogolla in La Rioja, Spain, dating back to the 11th century.

During the 16th and 17th centuries, the surname Olavarria appeared in various historical records and documents in the Basque Country and neighboring regions. One notable figure was Juan de Olavarria, a military commander who fought in the Conquista of the Canary Islands in the late 15th century.

In the 18th century, the Olavarria surname gained prominence in Argentina, particularly in the province of Buenos Aires. This can be attributed to the migration of Basque settlers to the region during the Spanish colonial era.
