Wanette is a town in Pottawatomie County, Oklahoma, United States. The population was 279 at the time of the 2020 Census. Wanette is part of the Purcell-Lexington retail trade area and is within the Greater Oklahoma City Metropolitan Area.

The first settlement took place in 1868, when two settlers from Kansas built a two-story cabin. Other settlers followed. The community had several different names before a post office named Wanette opened on March 19, 1894. In 1903, the town moved one mile north to be on the Atchison, Topeka and Santa Fe Railway line between Newkirk and Pauls Valley

By 1907, Wanette had a population of 739. The population peaked at 783 in 1920. The local economy was based on agriculture. Discovery of the Wanette-Asher oil field aided the economy during the 1930s, but did not prevent a population decline. The town still has an agricultural base, but by the beginning of the 21st Century had become a bedroom community for people working in Moore, Norman and Oklahoma City.

According to the United States Census Bureau, the town has a total area of 0.4 square miles (1.0 km), all land.
