Toribio de Luzuriaga y Mejía (16 April 1782 – 1 May 1842) was a Peruvian-Argentine soldier and the first Grand Marshal of Peru.

When Gabriel de Avilés was appointed Viceroy of Peru in 1801, Luzuriaga preferred to remain in Buenos Aires and decided to embrace a military career by entering the cavalry volunteer regiment of Buenos Aires.

He participated in the military campaigns against the Spanish royalists in Upper Peru, then in 1812 was appointed governor of the Corrientes Province.

[3] With the departure of José de San Martín from Peru, Luzuriaga lost his main supporter and decided to return to Argentina and retire from public life.

Fallen into oblivion and poverty, he died in Pergamino, in the province of Buenos Aires, on 1 May 1842 by shooting himself in the head.
