Phalanx is an unincorporated community located within Colts Neck Township in Monmouth County, in the U.S. state of New Jersey.[1] It is located near the Swimming River Reservoir and is across from Brookdale Community College in Lincroft. The community is named for the North American Phalanx, a communal agricultural community that existed in the 19th century. The community disbanded in 1854 following a fire[2] but the main residence stood until November 14, 1972 when another fire destroyed it.[3] Homes began to replace the former farmland beginning in the late 1970s and is now the primary composition of the area.[4]
