The massacre of Phocaea occurred in June 1914, as part of the ethnic cleansing policies of the Ottoman Empire that included exile, massacre and deportations. It was perpetrated by irregular Turkish bands against the predominantly ethnic Greek town of Phocaea, modern Foça, in the east coast of the Aegean Sea. The massacre was part of a wider anti-Greek campaign of genocide launched by the Young Turk Ottoman authorities, which included boycott, intimidation, forced deportations and mass killings; and was one of the worst attacks during the summer of 1914.

The 1914 Greek deportations was the forcible expulsion of around 150,000 to 300,000 Ottoman Greeks from Eastern Thrace and the Aegean coast of Anatolia by the Committee of Union and Progress that culminated in May and June 1914. The deportations almost caused war between Greece and the Ottoman Empire and were an important precursor to the Armenian genocide.
