The Union County Courthouse is a courthouse in El Dorado, Arkansas, United States, the county seat of Union County, built in 1927. It was listed on the National Register of Historic Places in 1983. The courthouse was built in the Classic Revival and Greek Revival styles by Mann & Stern and anchors the center of Union Square.
Union County was established in 1829 from Hempstead County and Clark County. The county seat began at Ecore Fabre and was moved to Scarborough's Landing. Cotton farmers again requested the county seat to move in 1843. It was moved to the county's highest point and was platted as El Dorado.[1]

Inside the courthouse is a two-story marble art deco atrium of marble and a courtroom with walnut wainscoting, a plaster ceiling featuring gilded rosettes and walls textured to resemble stone.
