Hermógenes López (19 April 1830, in Naguanagua, Carabobo – 17 December 1898, in Valencia, Carabobo) was a Venezuelan soldier, farmer and acting president of his country between 1887 and 1888, after the resignation of General Antonio Guzmán Blanco who went into voluntary exile in Paris.

There is scarce information about his childhood, which appears to have been limited to elementary education and farm work.

López, was the head of Carabobo state after an electoral fight against General Gregorio Cedeño (May 1881).

Hermógenes López's provisional government enjoyed the active cooperation of the Liberal Party and the society.

During his term in office, he inaugurated the railroad between Puerto Cabello and Valencia and an underwater cable with Europe (February 1888).
