Victorio's War, or the Victorio Campaign, is an armed conflict between the Apache followers of Chief Victorio, the United States, and Mexico beginning in September 1879.

Following his escape from the San Carlos Indian Reservation in southeastern Arizona, Victorio leads a guerrilla war across the Southwest and northern Mexico.

Many engagements are fought until the Mexican Army kills Victorio and defeats his warriors in October 1880.

After Victorio's death, Chief Nana continues the war into 1881.

Following the Battle of Cibecue Creek, in August 1881, Nana and his band join Geronimo.
