In its earliest origins, the town was known as Amancio Cué. In 1786 the city became the site of a Jesuit Mission founded by Father Juan Francisco Amancio González y Escobar with the name Reducción Melodía (Melody Mission) in honor of the Governor Pedro Melo.
The town was re-established during the 1841-1862 government of Carlos Antonio López and renamed Nueva Burdeos (New Bordeaux) by a colony of 120 French families. However, it did not prosper and was founded again the next year as Villa Occidental (Western Town). In the late 1860s, when Argentine soldiers occupied the city during the Paraguayan War, they called it Villa Argentina.
Finally, the city was named Villa Hayes, in accordance with the decree signed by President Cándido Bareiro, on May 13, 1879. This name was chosen to honor of the United States President, Rutherford Hayes, who on November 13, 1878, had been asked to arbitrate between Paraguay and Argentina after the Paraguayan War. His award of the disputed Gran Chaco region to Paraguay made him a national hero.
