About Onslow

Tucked into the rolling farmland of Jones County, Onslow is a quiet rural community with deep eastern Iowa roots. Founded in 1871, the town briefly went by Franksville before taking its current name in honor of Maine's first governor. Today, it offers a relaxed, open setting with a compact Main Street and quiet residential lanes. Residents enjoy the peaceful country atmosphere while still staying within an easy commute of Cedar Rapids, Dubuque, and nearby regional hubs.

Families in Onslow send their kids to the Midland Community School District, with local bus routes connecting directly to schools in nearby Wyoming and Oxford Junction. Daily life here revolves around friendly neighbors, a local cafe, and casual get-togethers at the city park on the south end of town. For anyone searching for affordable space, peace and quiet, and a tight-knit Midwestern community, Onslow is an easy place to settle down.
