Ames is a town in southeastern Major County, Oklahoma, United States. The population was 239 at the 2010 census. This was a 20.1 percent increase from the figure of 199 in 2000.

Ames is best known for being located within the boundary of a geological structure that is called the Ames crater or the Ames Astrobleme. The Ames Astrobleme Museum is located in the town.

Ames was founded at the opening of the Cherokee Outlet on September 16, 1893. It was initially named Hoyle, for a nearby creek. The Blackwell, Enid and Southwestern Railroad (later the St. Louis and San Francisco Railway) constructed a line from Blackwell in Kay County to Darrow in Blaine County, that passed through the community. On January 4, 1902, it was named for Henry S. Ames, a railroad official.

Ames had a population of 278 at the 1920 census and 332 at the 1940 census, its peak population.

Oil was discovered within the Ames crater in 1991.

Ames is located about 93 miles from Oklahoma City, 27 miles from Enid and 22 miles from Fairview (driving distances).

According to the United States Census Bureau, the town has a total area of 0.3 square miles (0.78 km), all land.

Every year in the month of August, the town celebrates Ames Day, both to commemorate the founding of the town and to raise funds for the town's volunteer fire department. Ames Day celebrations have been known to include parades, golf tournaments, pie auctions, turtle races, greased pig chases, mutton busting competitions, chicken roping, cow patty bingo, tug of war competitions, baseball games, beard-growing contests, and husband-calling competitions.

The Ames Astrobleme Museum, which opened August 18, 2007, features numerous image panels and a video showing the formation of the Ames crater and its discovery as a significant geological and economic resource. The crater was caused by a meteor striking the area 450 million years ago. There is sediment two miles deep covering the crater, and the town of Ames approximately is located in the middle of the crater. The crater is eight miles in diameter and is similar to craters on the moon. It is one of the few oil-producing craters in the world. Cumulative production figures through the end of 2006 show production in the Ames crater area approaching 11 million barrels.
