John I de la Roche (died 1280) succeeded his father, Guy I, as Duke of Athens in 1263.
In 1275, John, with 300 knights, relieved Neopatras, which had been blockaded by a Byzantine mercenary army.
The next year (1276), the Byzantine Emperor Michael VIII Palaeologus invaded Euboea and Thessaly.
John joined Gilbert of Verona to march to the relief of Negroponte, which was under attack by Licario.
During a battle six miles to the north, at Vatonda, John was thrown from his horse and captured, along with Gilbert and many other knights.
