Gallatin is a city in Daviess County, Missouri, United States.

[5] The territory now known as the county of Daviess, was initially inhabited by the Sauk, Meskwaki, and Pottawatomi peoples.

About 200 people attempted to forcibly prevent Latter-day Saints (also known as Mormons) from voting in the newly created county's first election.

In October 1838, David W. Patten led Mormon troops in the Daviess County expedition in which the Mormons burned and looted much of Gallatin, Millport and Grindstone Fork, consecrating the stolen goods to the bishop's storehouse.

Gallatin is important in the Latter-day Saint religion; nearby is a place known to its members as Adam-ondi-Ahman.

They believe it to be the site where Adam and Eve lived after they had been expelled from the Garden of Eden.

[12] On December 7, 1869 Jesse James (and most likely Frank) robbed the Daviess County Savings Association.

Jesse is believed to have shot and killed the cashier, Captain John Sheets.

The Daviess County Rotary Jail and Sheriff's Residence, the A. Taylor Ray House and the Daviess County Courthouse are listed on the National Register of Historic Places.

30.3% of all households were made up of individuals, and 14% had someone living alone who was 65 years of age or older.
