The Raid on Uchiza (Spanish: Incursión senderista a Uchiza) or Siege of Uchiza (Spanish: Sitio de Uchiza) also know Attack on the Uchiza police post (Spanish: Ataque al puesto policial de Uchiza de 1989) or Uchiza massacre (Spanish: Masacre de Uchiza de 1989) was an attack that occurred between March 27 and 28, 1989, carried out by the Popular Guerrilla Army of the Shining Path (with the support of drug traffickers and M-19 cells from Colombia) against the DOES-6-Uchiza Base of the Peruvian National Police (PNP). The attack was intended to expel the Peruvian State from the Alto Huallaga ensuring control of Uchiza to have free passage to Madre Mía,^[1] one of the largest bases of the Peruvian Armed Forces in the San Martín region.

Uchiza was located at a strategic point in the province of Tocache, nestled in the "Alto Huallaga front", dominated by the Communist Party of Peru-Shining Path^[2] during the era of terrorism in Peru.^[3] Although its position was crucial for the Peruvian State, it was modestly defended only by the police base DOES-6-Uchiza with fifty to sixty troops.^[1] The massive attack by the Shining Path resulted in the death of ten police officers, and fourteen others were wounded. The People's Guerrilla Army summarily executed three prisoners of war,^[2] an act that the Truth and Reconciliation Commission described as a war crime.^[1]
