Julio Arboleda Pombo (9 July 1817, Barbacoas, Viceroyalty of New Granada – 1862) was a Colombian poet, journalist, and politician.

He was also a prominent slave owner and led a failed rebellion in 1851 with the aim of preventing the abolition of slavery in the country.

With the support of the states of western Colombia, he assumed supreme power, but soon afterwards was assassinated, by political enemies it is supposed.

Titles include "Dios y la virtud" (God and virtue), "Estoy en la cárcel" (I am in jail), "Me ausento" (I leave), "Te quiero" (I love you) and the long one called "Gonzalo de Oyón" (Gonzalo of Oyón).

The manuscript of "Gonzalo de Oyón", called by some his most important work, was almost completely destroyed by an opponent, and only fragmentary copies are preserved.
