[3] In 1906, delegates to Constitution Convention formed Garvin County from part of the Chickasaw Nation, Indian Territory.

The county was named for Samuel J. Garvin, a local Chickasaw rancher, merchant and banker.

[1] Garvin County came into existence on November 16, 1907, the day Oklahoma became a state.

The Golden Trend pool, which ran from the northwest to the southern parts of the county developed later.

[5] The county lies between the Red Bed plains and the Sandstone Hills physiographic regions.

While oil and gas production are important to the county economy, agriculture has been the major industry for employment since statehood.

In 1907 crops of alfalfa, broomcorn, cotton, onions, potatoes, and hay produced in the county were valued at $2.5 million.
