The Yalova Peninsula massacres (Turkish: Yalova katliamı, lit. 'Yalova massacre') were a series of massacres during 1920–1921, the majority of which occurred during March – May 1921. They were committed by local Greek, Armenian and Circassian bands, "assisted by drunken and undisciplined Greek troops", against the Muslim Turkish population of the Yalova Peninsula. There were 27 villages burned and in Armutlu. According to journalist Arnold J. Toynbee c. 300 Muslims were killed during April–July 1921. In an Ottoman inquiry of 177 survivors in Constantinople, the number of victims reported was very low (35), which is in line with Toynbee's descriptions that villagers fled after one to two murders. Moreover, approximately 1,500 out of 7,000 Muslims remained in the region after the events or 6,000 had left Yalova where 16 villages had been burned. On the other hand, Ottoman and Turkish documents on massacres claim that at least 9,100 Muslim Turks were killed.

The high death toll in the events convinced Toynbee that the Greeks were unfit to rule over Turks. An Inter-Allied commission, consisting of British, French, American and Italian officers, and headed by Maurice Gehri, the representative of the Geneva International Red Cross, and Arnold Toynbee went to the region to investigate the atrocities.

One of the results was that refugees were transported to Allied-controlled Constantinople on ships.
