Clovis Man inhabited the Blackwater Draw area north of Portales until 11,000 years ago.

Semi-nomadic non-Pueblo Southern Athabaskan groups (Apache, Navajo) occupied much of the area as early as the 13th century. In the early 18th century, the Comanche displaced the Apache who had previously lived in this region. The Comanche commanded the area until late in the 19th century.

The surrounding area of eastern New Mexico is part of what came to be known in the colonial period during Spanish rule as the "Llano Estacado", an arid and treeless plateau bounded on the north and west by the Caprock Escarpment stretching south from the Canadian River and east along the Pecos River. The Spanish soldier and explorer Francisco Vázquez de Coronado, the first European to traverse the area in 1541, named the region after seeing these cliffs. From the north they resemble a stockade ("estacada") surrounding the high table-land, thus the name, meaning "Stockaded Plain" or "Palisaded Plain."

The US territorial settlement of Portales occurred in the late 19th century as cattle herders discovered a water source emanating from a rocky ledge resembling a Spanish porch. The local watering hole took on the name "Portales", and a few settlers began ranching nearby. The City of Portales was formally established in 1909 with the arrival of the railroad to the southwestern High Plains. The first Mayor of Portales was Washington Ellsworth Lindsey, who later became a state Governor of New Mexico.

The town developed in an orderly fashion through the early 20th century. In particular, given its access to the Ogallala Aquifer, improved surface irrigation techniques supported steady growth in agriculture.

Eastern New Mexico University was established in 1934 as a teacher's college. Originally a junior college, it became a four-year institution in the mid-20th century. The Great Depression brought several important Works Progress Administration (WPA) construction projects including the Eastern New Mexico University Administration Building, the downtown Portales Post Office, and the Roosevelt County Courthouse. All three buildings are listed on the National Register of Historic Places.
