Gen. Benjamín Guillermo Hill Salido (31 March 1874 – 14 December 1920) was a military commander during the Mexican Revolution.

He was a cousin of revolutionary general and later president Álvaro Obregón Salido, whom he supported from the beginning of his rise to power.

He fell in love with an Italian countess, whose family objected to the match, but the couple eloped and returned to Mexico.

"[6] In 1912, he fought against the rebellion led by Pascual Orozco and, following the 1913 coup d'état of Victoriano Huerta, he joined the northwestern corps of the Constitutionalist Army, which would ultimately be commanded by his kinsman Álvaro Obregón.

[3] Obregón had not joined the early Maderista phase of the revolution, but once he did, Hill supported his rise in military ranks despite grumblings of some who had fought for Madero.

[7] Hill was an extremely able Constitutionalist Army commander, put in charge of Mexico City in 1915.

Hill was one of the main proponents of the Plan of Agua Prieta, fighting in the military rebellions that ensued.

He was seen as a potential presidential successor to Obregón, which brought him into conflict with Interior Secretary Plutarco Elías Calles.
