Millburn was created as a township by an act of the New Jersey Legislature on March 20, 1857, from portions of Springfield Township, when Union County was formed. Earlier known variously as Milltown, Millville, Rum Brook, and Vauxhall, the name "Millburn" was adopted before the township was established. The township's name derives from the burn (Scottish for a stream) that powered mills in the area.
