Retreat is an unincorporated community and former hamlet located within Southampton Township in Burlington County, in the U.S. state of New Jersey.

[4] The community was originally named New Retreat during the American Revolutionary War by a Continental Army soldier who used the site for a cannonball manufacturing.

The site was concealed from the British army who at the time was occupying present-day Mount Holly.

Retreat was later home to cotton mills which operated until the 1840s.
