The 1980 Ispaster attack was a gun and grenade attack by the Basque separatist organisation ETA which occurred on 1 February 1980 near the Basque town of Ispaster. The targets were a convoy of civil guards who were escorting workers and weapons from the nearby Esperanza y Cia Arms factory to Bilbao. A total of six civil guards were killed, while two ETA members were killed by hand grenades that they had thrown. The attack was the deadliest of 1980, the year when ETA killed more people than any other.
