Francisco Nicolás Iturrino González (9 September 1864 – 20 June 1924) was a Spanish Post-impressionist painter of Basque ancestry.

In 1901, he had advanced to the point that he was able to show his work at the prestigious Vollard Gallery, alongside a then-unknown Pablo Picasso.

[2] He continued to travel throughout the Basque Country, France and Andalusia, which was his favorite place because of the landscapes, although he also painted bullfights, festivals and portraits of women.

From 1911 to 1912, he spent some time in Morocco with Henri Matisse, a close friend he had met in the workshops of Gustave Moreau, and who he often stayed with when visiting Paris.

The art historian, Élie Faure, helped organize an exhibition at the Galerie Rosenberg, featuring paintings donated by Matisse, Picasso and several other of Iturrino's friends.
