Alejandrina Benítez de Gautier[note 1] (February 26, 1819 – October 11, 1879)[1] was a Puerto Rican poet.

She moved to San Juan and lived with her aunt, the poet and author María Bibiana Benítez who raised her and looked after her education.

[1] Benítez de Gautier wrote a poem entitled La Patria del Genio (The Nation of the Genius) dedicated to Jose Campeche; for this poem she was awarded 100 Spanish pesos from the "La Sociedad Económica Amigos del País" (Friends of the Economic Society of Puerto Rico).

In 1861, new poems by Benítez de Gautier which were published in the local journals began to appear.

In said poem she pays tribute to the knowledge and engineering that went into the establishment of telegraph service between Puerto Rico and St. Thomas.
