Swatara is an unincorporated community in Macville Township, Aitkin County, Minnesota, United States.

Swatara and neighboring townships were considered as a potential location of the Minnesota Experimental City that was proposed by scientist Athelstan Spilhaus in the 1970s.

Despite support from state legislature, and prominent companies such as Ford, Boeing, and Honeywell, Aitkin County residents pushed back against the proposed city, citing environmental concerns as well as concerns about changing their way of life.

The newly formed Minnesota Pollution Control Agency voted to abandon the project in 1973.

Nearby places include Hill City, Remer, and Haypoint.
