Felipe Esteban Llavallol (December 26, 1802 – April 4, 1874) was an Argentine merchant, philanthropist, lawmaker and briefly Governor of the secessionist State of Buenos Aires.

Following the September 11, 1852, declaration of the secessionist State of Buenos Aires, Llavallol held numerous posts in the new government.

He was appointed Economy Minister and took part in the establishment of the Buenos Aires Stock Exchange in 1854, and served as its first president until August 1855.

He stepped down on May 3, 1860, upon the legislature's election of Colonel Bartolomé Mitre, who defeated Confederate forces at the 1861 Battle of Pavón and reincorporated Buenos Aires into a unified Argentina.

Llavallol continued his work as a member of the Comisión Filantrópica charity organization, and died in Buenos Aires in 1874, at age 71.
