Brinkman is an unincorporated community in Greer County, Oklahoma, United States.

Brinkman was founded in 1910, and named after John Brinkman, who was a business associate of railroad builders Joseph A. Kemp and Frank Kell.

It was a market town for the surrounding area and had two large elevators as well as other amenities.

But the bank closed in 1927, and a fire destroyed half the town in 1929.

Oklahoma State Highway 34, constructed in 1931, bypassed the town to the east, accelerating the decline.
