Kintpuash, also known as Captain Jack (c.1837 – October 3, 1873), was a chief of the Modoc tribe of California and Oregon. He led a band from the Klamath Reservation to return to their lands in California, where they resisted return. From 1872 to 1873, their small force made use of the lava beds, holding off more numerous United States Army forces for months in the Modoc War.
