Juan C. Cailles (b. November 10, 1871 – d. June 28, 1951) was a teacher in Baryo Amaya, Tanza, Cavite when the revolution broke out. As a way of recruiting revolutionaries, he encouraged his pupils' fathers to fought the Spaniards and join the Katipunan.
In 1897, he was appointed brigadier general of the army under Gen. Emilio Aguinaldo, and was the commanding officer of Battalion Trias which fought major battles in Cavite and its periphery. He is one of the signatories in the declaration of Philippine independence on June 12, 1898. He was assigned in Laguna for a year, and in 1900, he was back in Cavite and defeated Spanish troops there. However, on June 24, 1892, he surrendered to the Americans, but this just opened his political career.
Cailles became civil governor of Laguna in 1902 to 1910, and later, as provincial governor for two terms in 1915 to 1925, and 1932 to 1938. From 1926 to 1931, he was elected as representative of Mountain Province. After such political positions, in 1940, he was assigned Vice-President of the Board of Pensions for Veterans, and as General Inspector of the Philippine Veterans Administration a year after.
