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.
New Jersey Monthly magazine ranked Millburn as the 53rd best place to live in New Jersey in its 2008 rankings of the "Best Places to Live" in New Jersey.
Millburn had the highest annual property tax bills in the U.S. state of New Jersey in 2009 at $19,097, compared to the statewide average of $7,300 that year, which was the highest in the United States. This is primarily a function of high property values, as Millburn had the lowest effective property tax rate in 2014 (1.9%) among the 22 municipalities in Essex County.
In June 2007, Millburn celebrated its 150th birthday in its downtown, in one of the biggest celebrations in Millburn history.

^History, Township of Millburn. Accessed September 7, 2015. "Millburn has had many names, from Rum Brook, Vauxhall, Milltown, and Millville. In 1857, 'Millburn' was decided upon, partly because many of the town's residents were from Scotland and the mill burn (Scotch word for 'river' or 'stream') reminded them of home. Later there were disputes over the spelling of Millburn, but the double-L advocates won."
