Aroya is a small, rural, unincorporated community in Cheyenne County, Colorado, United States at the eastern end of State Highway 94 near its junction with U.S. Highway 40/U.S. Highway 287. The name Arroyo appears on some older maps. The town was named "Aroya" because of a gulch nearby (arroyo is a Spanish word for "gulch"). The gulch is now named the Aroya Gulch. Aroya originated in 1870 three miles west of the present site as a camp for Kansas-Pacific Railroad track-layers, but was moved to the present site because there was a better supply of water.
