Frank Putnam Flint (July 15, 1862-February 11, 1929) was a politician and banker. He served as United States Attorney for the Southern District of California from 1897 to 1901 and as a U.S. Senator from California from 1905 until 1911. He was a Republican. He served one term in the Senate and did not run for reelection. The town of La CaƱada Flintridge, California is named for him (in part), as he was a developer of Flintridge, which merged with La CaƱada in the late 20th century. As Senator of California he played a great part in making the Mission style the official architectural style of government buildings in Southern California.
On his passing in 1929, Flint was interred in the Forest Lawn Memorial Park Cemetery in Glendale, California.
