Cayetano José Rodríguez (1761 – 21 January 1823) was an Argentine cleric, journalist and poet.
Rodríguez was born in San Pedro, Buenos Aires Province and was educated at a Franciscan school, joining the Order at 16.
Rodríguez was impressed by the patriots and revolutionaries of the early 19th century, even dedicating a poem to the slaves who helped defend the city against the British invasions.
He was elected by the city of Buenos Aires to the Tucumán Congress in 1815 and proposed a motion to set up a committee to prepare its constitution.
It is believed that Rodríguez may have written the declaration of independence himself, in his capacity as editor of the Congress' papers.
