John Calvin Coolidge Sr. (March 31, 1845 – March 18, 1926) was an American politician and businessman from Vermont, and the father of Calvin Coolidge, the 30th president of the United States. The senior Coolidge administered the presidential oath of office to his son at their family homestead in the early morning hours of August 3, 1923, following the death of President Warren G. Harding.

Born in Plymouth, Vermont, John C. Coolidge was a farmer and store owner, and worked at a variety of other occupations, including banker and insurance broker. In addition, he was a veteran of the Vermont militia, and held the law enforcement posts of town constable and county deputy sheriff. A prominent local leader, he served in numerous Plymouth town offices, and was elected to terms in both the Vermont House of Representatives and Vermont Senate.

John C. Coolidge remained active in his farming and business interests until his death in Plymouth in 1926; he was buried in Plymouth Notch at a village cemetery where several generations of his family are also buried.
