Marshalltown is an unincorporated community located within Mannington Township, in Salem County, New Jersey. It has also been known as Frogtown.

The community is centered at Marshalltown Road and Roosevelt Avenue, located 2.7 mi southeast of Glenside and 3.6 mi east-southeast of Pennsville.

History
Located near the Salem River, Marshalltown was one of five pre-Civil War communities developed along tributaries of the Delaware River by freedmen. It is named after Thomas Marshall (1803–1856), who purchased land here starting in 1834.

Before the abolition of slavery, these black-populated communities offered protection and aid to fugitive slaves, and "the likelihood that there was antebellum Underground Railroad activity is high".

The settlement once contained many houses and gardens, a school, stores, and two churches. Mount Zion A.U.M.P. Church in Marshalltown is one of the earliest African Methodist churches.

By 2010, only a school house, a church, and two cemeteries survived, and "isolation, theft, vandalism, and lack of historic preservation planning threaten the surviving cultural landscape of Marshalltown".
