Oklahoma towns list more on the Register than most of the country (a typical Oklahoma town has 5.9 per 10,000 residents, the U.S. 2.4), so Locust Grove’s 0.0 sits below most of its state (18% of Oklahoma towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

What stands out about Locust Grove’s past

Locust Grove was the site of the Battle of Locust Grove, a small Civil War engagement on July 3, 1862, in which approximately 250 Union troops surprised and destroyed a similar-sized Confederate contingent, killing about 100 and capturing another 100 while sustaining only minimal losses. The escaping Confederates retreated toward Tahlequah, leading to a loss of morale and desertions among the Cherokee Confederate supporters.
The Locust Grove post office opened in 1873, the earliest record of the town by name (U.S. post office records).
