Union County is a county located in the U.S. state of Arkansas. As of 2010, the population was 41,639. The county seat is El Dorado. The county was formed on November 2, 1829, and named in recognition of the citizens' petition for a new county, stating that they were petitioning "in the spirit of Union and Unity". The county is directly adjacent to Union Parish in the state of Louisiana.
The El Dorado Micropolitan Statistical Area includes all of Union County.
Union County/Union Parish Monument
In 1931, a monument was established at the Union County border with Union Parish, Louisiana, through the private efforts of former Arkansas Governor George Washington Donaghey (1856–1937), who was born in Union Parish and grew up in the border area before he moved as a teenager to Conway, Arkansas. As governor, he oversaw the construction of the state capitol building in Little Rock and brought about the establishment of the state health unit and its agricultural colleges. After his gubernatorial tenure, Donaghey, who felt a kinship to both states, commissioned a park on the land about the monument. Known for its intricate carvings and Art Deco style, the monument includes references to different modes of transportation a century apart—1831 and 1931—and mentions Huey P. Long, Jr., whose educational program Donaghey admired. The land was not registered with the state parks offices in either state, timber companies cut trees thereabouts, and the monument was forgotten. In 1975, State Representative Louise B. Johnson obtained passage of a law to refurbish the monument. Resoration efforts were finally unveiled in 2009.
According to the 2000 census, the county has a total area of 1,055.27 square miles (2,733.1 km2), of which 1,038.90 square miles (2,690.7 km2) (or 98.45%) is land and 16.37 square miles (42.4 km2) (or 1.55%) is water. Union County, along with Columbia County, has the largest bromine reserve in the United States. The lowest point in the state of Arkansas is located on the Ouachita River in Union County and Ashley County, where it flows out of Arkansas and into Louisiana.

Townships have limited purposes in modern times. However, the US Census does list Arkansas population based on townships (often referred to as "minor civil divisions"). Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps.
