Crystal Hill is an unincorporated community in Hill Township, Pulaski County, Arkansas, United States. It is located along Crystal Hill Road near the junction of Interstate 40 (I-40) and I-430.
When the Arkansas territorial legislature decided to move the capital from Arkansas Post in 1820, governor James Miller purchased land on Crystal Hill in an effort to profit by later selling it to the government as the new state capital. However, the final vote was between Little Rock and Cadron, a vote that selected Little Rock as territorial capital. Miller built a house and lived at Crystal Hill in protest until being appointed Collector of Customs in Salem, Massachusetts by James Monroe. Crystal Hill was never platted or incorporated.
