Eastborough is a city in Sedgwick County, Kansas, United States, and an enclave of the city of Wichita.
Eastborough was originally envisioned by Burdon Hunter, a British architect. The first development in the Eastborough area began in 1929, but the discovery of oil in the area postponed its establishment until the middle of the 1930s. Sale of Eastborough Village started April 10, 1929. It was planned to incorporate when the first thirty homes were completed, but Eastborough found itself in disputes with the neighboring Woodlawn subdivision, i. e. they could not agree upon a name for the street between them. The disputes were resolved after the two agreed to apply together for incorporation, and Eastborough and Woodlawn were incorporated as the city of Eastborough on June 1, 1937
