Francisco Narciso de Laprida (October 28, 1786 in San Juan – September 22, 1829)[1] was an Argentine lawyer and politician.

Because of his education in law and as an important local figure, he was sent to the Tucumán Congress in 1815 as provincial deputy, together with Fray Justo Santa María de Oro.

He returned to San Juan at the end of the deliberations, where he served as acting governor replacing José Ignacio de la Roza.

At the end of his internship he represented his province again in 1824 at the General Constituent Congress, being its president for some months.

On September 22, 1829, the men of José Félix Aldao, shortly after defeating the unitarian commander Juan Agustín Moyano, reached Laprida's coach and slit his throat; his body was never found.
