Count of Osorno
Count of Osorno is a Spanish hereditary peerage that was granted on 31 August 1445 by John II of Castile to Gabriel Fernández Manrique, 1st Duke of Galisteo. The title is accompanied by the dignity of Grandee of Spain.
On the death in 1675 of Ana Apolonia Manrique de Lara, 8th Countess, and in the absence of an heir, the title went to the House of Alba, which still holds it.
The name of the title refers to the municipality of Osorno la Mayor in the province of Palencia, Castile and León, Spain.
