The surname Diago originated in Spain during the Medieval period. It is believed to have derived from the Spanish given name "Diego," which itself has Latin roots tracing back to the name "Didacus." The name Didacus is thought to have been derived from the Greek word "didaktos," meaning "taught" or "instructed."

One of the earliest recorded instances of the surname Diago can be found in the Codex Calixtinus, a 12th-century manuscript that includes a record of pilgrims traveling the Camino de Santiago. This document mentions a pilgrim named Petrus Diago who made the journey to Santiago de Compostela in 1137.

The Diago surname is also present in several medieval Spanish documents, including a 14th-century record from the city of Seville that mentions a landowner named Juan Diago. Another notable early bearer of the name was Rodrigo Diago, a 15th-century Spanish explorer who accompanied Christopher Columbus on his second voyage to the Americas in 1493.

In the 16th century, the Diago surname can be found in records from the Spanish region of Aragon, where it was particularly prevalent in the town of Calatayud. One notable figure from this area was Pedro Diago, a historian and clergyman born in Calatayud in 1555, who wrote extensively about the history of the region.

During the 17th century, the Diago surname spread to other parts of Spain, including the Canary Islands. A prominent individual from this era was Alonso Diago, a Canarian poet and playwright born in 1620, whose works helped to popularize the use of the local dialect in literature.

In the 18th century, the Diago surname can be found in records from the Spanish city of Valencia, where a family of notable architects and builders bore this name.
