The Kibi Revolution (Japanese: キビ カクメイ (己未革命) Kibi Kakumei, "Revolution of the Year of Yin Earth Goat"), also known as the Japanese Revolution of 1919, was a series of civil conflicts and disturbances in Japan between 1919 and 1920.

It first took place as a protest against the government policy that resulted to the country-wide economy crisis in Tokyo on November 13, 1919 which bloodily suppressed by the Imperial Guards. The civil disturbance soon became widespread throughout Japan where included worker strikes, peasant unrest, and military mutinies. The revolution was named Kibi because it occurred in 1919, the year of the Jiwei stem-branch ("Kibi" in Japan) in the traditional sexagenary cycle of the Chinese calendar.

The revolution mainly arose due to popular dissatisfaction of country's expansionist policies from 1898 to 1905 which resulted Japan being hampered by a deep economic crisis and also partially as an extension of the 1865–67 Japanese Civil War where the revolution is viewed as a continuation of conflicts between the Nationalists and the Liberals over the control of Japanese state.
