Gunter was founded in 1902 (other sources report 1901, with a post office as early as 1898) when the family of John (a/k/a Jot) Gunter deeded 328 acres (1.33 km2) for the original townsite, near the intersection of State Highway 289 and Farm to Market Road 121. The first residence was established in 1903 by Albert Earthman, who would later charter the First National Bank in Gunter. A second bank, the First State Bank, would later open.Gunter steadily grew until 1924, when the First State Bank (having outlasted the First National Bank) closed its doors, leaving many businessmen and farmers in financial ruin. The Great Depression and two devastating fires in 1930 and 1948 further damaged the local economy.
