The Oklahoma–Arkansas–Kansas League was an eight-team Class-D minor baseball league that existed in 1907. As its name indicates, it consisted of teams from Oklahoma, Arkansas and Kansas.
Its teams were the Bartlesville Boosters, Coffeyville Glassblowers, Fort Smith Soldiers, Independence Champs, McAlester Miners, Muskogee Redskins, Parsons Preachers and Tulsa Oilers.
Notable players include Chick Brandom, Drummond Brown, Larry Cheney, Frank Moore, Art Thomason and Lon Ury.
After multiple teams disbanded and withdrew, the league's season was shortened to mid-September. Bartlesville finished in first place.
