Champion Of Death (けんか空手 極真拳, Kenka karate kyokushinken, literal translation: Fighting Karate Kyokushin Fist), also known as Karate Bullfighter, is a Japanese martial arts film made by the Toei Company in 1975. It was the first in a trilogy of films based on the manga Karate Baka Ichidai (literal translation: A Karate-Crazy Life), a manga based on Masutatsu Oyama's life by Ikki Kajiwara, Jiro Tsunoda and Jōya Kagemaru.

Sonny Chiba stars as his former master Oyama who was the founder of Kyokushin karate. Chiba would reprise this role in two more films Karate Bearfighter (1975), and Karate for Life (1977).
