The Kantō Massacre (關東大虐殺, Korean: 간토 대학살) was a mass murder in the Kantō region of Japan committed in the aftermath of the 1923 Great Kantō earthquake. With the explicit and implicit approval of parts of the Japanese government, the Japanese military, police, and vigilantes murdered an estimated 6,000 people: mainly ethnic Koreans, but also Chinese and misidentified Japanese, and Japanese communists, socialists, and anarchists.

The massacre began on the day of the earthquake, September 1, 1923, and continued for three weeks. A significant number of incidents occurred, including the Fukuda Village Incident.

Meanwhile, government officials met and created a plan to suppress information about and minimize the scale of the killings. Beginning on September 18, the Japanese government arrested 735 participants in the massacre, but they were reportedly given light sentences. The Japanese Governor-General of Korea paid out 200 Japanese yen in compensation to 832 families of massacre victims, although the Japanese government on the mainland only admitted to about 250 deaths.

The massacre has since been continually denied or minimized by both mainstream Japanese politicians and fringe Japanese right-wing groups. Since 2017, the Governor of Tokyo Yuriko Koike has consistently expressed skepticism that the massacre occurred.
