Browns Mills is a central New Jersey suburb located within Pemberton Township, adjacent to Joint Base McGuire-Dix-Lakehurst. The community is almost entirely residential, with residential neighborhoods full of single-family homes occupying much of the landscape. The long and narrow Mirror Lake bisects the town, with the north side being much more densely populated than the south side.

Thanks to the close proximity to the Joint Base, Browns Mill is a popular spot among armed service members seeking off-base housing, as well as civilian military employees and support personnel. Living in Browns Mill also offers terrific access to the natural beauty of the region, with the vast Brendan T. Byrne State Forest just minutes to the south.
