Putnam County is a county in north central Missouri. At the 2020 census, the population was 4,681. Its county seat is Unionville. The county was organized February 28, 1845, and named for Israel Putnam, a hero in the French and Indian War and a general in the American Revolutionary War.
Putnam County was established February 28, 1845, from parts of Adair and Sullivan counties. The following year a portion of Putnam was removed to form Dodge County. Both Putnam and Dodge extended nearly nine miles further north until an 1851 ruling by the Supreme Court on a border dispute with Iowa assigned the contested land to Iowa. Both counties were left with less than the statutory minimum area for a county as set by the state legislature, so Dodge County was dissolved and its area added to Putnam.
