Hermógenes López Coarchita (16 September 1928 - 30 June 1978) was a GuatemalanRoman Catholic priest. He served as the pastor for the San José de Pinula parish since the late 1960s until his murder in mid-1978 due to his consistent championing of human rights and in particular his demand that all Guatemalans have the basic right to access clean water. His constant speaking out against corruption and regime abuses led to his enemies planning to kill him in an effort to subdue potential rebellion in the region.
