(Russian: 1828-1905) was a Russian painter, known for his paintings of seascapes.
Lagorio was born in Feodosia, Crimea (now Ukraine) and later studied in the Imperial Academy of Arts in Saint Petersburg. His teachers were Maxim Vorobiev and B. P. Villeval'de. While he lived in Feodosia, he was influenced by the painter Ivan Aivazovsky. In 1845 Lagorio went on a sea voyage on the warship Groziashchy to study the arrangement of the ship.
Lagorio spent eight years in Italy. The paintings he created there brought him to the status of professor on his return home to Russia.
In his later years, he painted the coastal views of Finland and Norway. He also painted motives of the Russian-Turkish war.
