Fermín Rojas Pacheco (Chiapas, 1928 - ?) was a painter whose talent has fallen into obscurity. He studied at the Escuela de Artes Plásticas de Chiapas (Chiapas School of Fine Arts) and, in 1948, enrolled in the Escuela Nacional de Artes Plásticas (National School of Fine Arts). During his training, he studied printmaking under Carlos Alvarado Lang and worked as an assistant to José Chávez Morado. In 1952, he joined the  Frente Nacional de Artes Plásticas (National Front of Fine Arts) and participated in the Pinturas y grabados mexicanos (Mexican Paintings and Prints Exhibition) exhibition in 1955.

In 1959, his work was featured in Pinturas y grabados mexicanos (Mexican Paintings and Prints Exhibition) at the Casa Regional Valenciana (Regional Valencian House). By the late 1980s, his work was represented by the Galería Theo Obras Originales (Theo Gallery Original Works), first located in the Doctores neighborhood and later in Santa María la Ribera, Mexico City.

A defining feature of his work is that his characters almost always appear with their backs turned, with rare pieces depicting frontal features. Although his body of work is extensive and has been reappraised in collective exhibitions, a solo exhibition showcasing the best of his career remains long overdue.
