Allen Trimble (November 24, 1783 – February 3, 1870) was a Federalist and National Republican politician from Ohio.

[2] In October 1784, his father moved his family to a veterans land grant in then Fayette County, Kentucky.

He then retired to farming, taking little part in politics for the next quarter-century, but did consent to accepting the nomination of the Know-Nothings for governor in 1855.

Trimble came in third, losing to Republican US Senator Salmon Chase and incumbent Democrat William Medill.

[4] Trimble's daughter, Eliza, helped to initiate the temperance movement in the United States.
