Castleton is a neighborhood area in Lawrence and Washington townships on the northeast side of Indianapolis, Indiana, United States.

Historically, the former Town of Castleton was platted near present-day 82nd St. and the former Nickel Plate Road, about 12 miles (19 km) northeast of downtown Indianapolis.

In the proceeding decades, the town saw gradual development, with a church, grade school, grain elevators, and a railroad depot.

[2] In 1965, county officials rezoned the area for commercial and light industrial land uses in anticipation of the local Interstate Highway System.

Suburban development accelerated upon the mall's opening, with the construction of several single-family subdivisions, apartment complexes, shopping centers, and office parks in the 1980s and 1990s.
