As early as 1918, Baroy was originally called Baloy, a plant commonly found in the community that is used for mat weaving. Later on, the said plant became extinct and the inhabitants of the locality decided to change the name to Baroy. The municipality of Baroy was formerly a mere barrio of the municipal district of
Kolambugan. When
Tubod was separated from Kolambugan (Republic Act No. 58, October 17, 1946), the barrios of Baroy, Sagadan, and Princesa were brought along with it. It became a regular municipality on June 10, 1949, by virtue of Executive Order No. 222 during the term of President Elpidio L. Quirino. The act stated that the municipality of Baroy would be separated from Tubod, and that parts of Kolambugan would be annexed to the two towns. On January 13, 1960, the town of
Salvador was separated from the town through Executive Order No. 370. Baroy celebrates
Lechon Festival every 10th day of June. ==Geography==
