Henry II (18 April 1503 – 25 May 1555), nicknamed Sangüesino because he was born at Sangüesa, was the King of Navarre from 1517, although his kingdom had been reduced to a small territory north of the Pyrenees by the Spanish conquest of 1512.
Henry succeeded his mother, Queen Catherine, upon her death.
His father was her husband and co-ruler, King John III, who died in 1516.
