Pablo Lucero (c. 1800 - 12 September 1856) was an Argentine soldier, a leader of the Federalist Party, and governor of San Luis Province throughout the 1840s.

He raised new forces and called to his aid the Mendozan José Félix Aldao and General Pablo Alemán, who accompanied him to victory in the Batalla of Las Quijada.

He immediately joined Aldao's army in defense against the invasion of San Juan by the Unitarian General Gregorio Aráoz de Lamadrid.

Trade, livestock and agriculture flourished, while the governor remained at peace with the central government of Juan Manuel de Rosas.

Aided by his Minister Juan Carlos Rodríguez he founded some schools and refounded several villages that had been destroyed by the Indian raids.

[citation needed] In November 1854, Lucero left the province in the hands of Justo Daract, a progressive liberal who took the middle ground between the Unitarians and Federalists.
