Charles Nelson Lamison (c. 1826 – April 24, 1896) was an American politician, soldier, and lawyer who was a two-term United States congressman from Ohio.

Born in Columbia County, Pennsylvania, Lamison moved with his father in 1836 to Dalton, Ohio, where he was privately instructed in elementary branches.

At the outbreak of the Civil War, Lamison enlisted in the Union Army and was elected as the initial captain of Company F of the 20th Ohio Infantry, serving in Northern Virginia.

After the close of the war, he resumed practicing law in Lima and was an unsuccessful Democratic candidate for the United States House of Representatives in 1866.

Lamison died in Topeka, Kansas, on April 24, 1896, and was interred in Woodlawn Cemetery in Lima, Ohio.
