Rio Grande, New Jersey

Rio Grande is an unincorporated community and census-designated place (CDP) located within Middle Township and Lower Township in Cape May County, in the U.S. state of New Jersey.

Though for the 1990 to 2010 U.S. censuses the CDP was entirely located within Middle Township, a small section at the southern edge of the community, located in Lower Township, is sometimes called Rio Grande. For the 2020 U.S. Census the boundary was redrawn so that portions of Lower Township were included in the Rio Grande CDP.

It is part of the Ocean City Metropolitan Statistical Area. As of the 2010 United States Census, the CDP's population was 2,670.

History
According to Jeffrey M. Dorwart, Rio Grande was founded in the mid-nineteenth century around a country store owned by the Hildreth family. The community was originally called Hildreth for that reason.

George F. Boyer and J. Pearson Cunningham explain that, during the colonial period, Aaron Leaming, the Hildreths and the Cresses had plantations in that area. Where the King's Highway crossed the road coming from Dennisville and Goshen a stage coach terminal was set up, and the spot became the center for trade for the local farming families. Boyer and Cunningham say that the area was known as "Leamings," for the prominent landholders, or as "Hildreth," the family who ran the local store. (p. 121-122) They continue, "The name, Rio Grande, was suggested by the seventh Aaron Leaming who thought this southern United States river had an attractive sound."
