Formerly a part of Cauayan, Hinoba-an was inhabited by natives called "Magabat". When immigrants from Panay came and settled in the coastal areas, the settlers began to group in the area where the town is now located. Traders visited to barter products like clothing made in Miag-ao, Tigbauan and Guimbal in Iloilo.

Spanish authorities did not occupy Hinoba-an during their time in the province since the area was still a jungle. It was visited only by people from Cauayan and the neighboring towns for hunting purposes, hence no important events were recorded about the coming of the Spaniards in the town until the early 20th century.

In the early 1900s, Don Estanislao Bilbao, a Basque émigré and patriarch of the Bilbao clan---one of the area's prominent families, begun a decades-long process of settling an area south of where Hinoba-an would come to be. In a few years, a significant plot of land had been rehabilitated to which thousands of germinating coconut husks were planted in precise rows. Maturing and bearing crop in under a decade, once coastal wilderness was transformed into copra producing land. Paddy fields were likewise developed further inland close to irrigation sources.

The subsequent grant of landownership, along with the total absence of government due to the area's remoteness, it became the basis for Don Estanislao's provisional administration of the people and the place. He became the area's primary, if not for a time, sole employer. As a matter of moral imperative and practical necessity, he also became the de facto Judge and Sheriff, adjudicating upon and enforcing common law.

Through his marriage to Felicidad Rivas—a patrician heiress to a similarly homesteaded parcel of land nearby, Don Estanislao doubled the size of the holding. Hand-in-hand with Dona Felicidad, they lorded over a highly productive agricultural expanse that, from points north to south, ostensibly stretched for miles on end. The couple's lifelong beneficence and philanthropy endeared them to the local populace making the Bilbao name well-respected and well-loved. Sons Joaquin and Francisco, and daughter-in-law Teresa, have each been elected town's mayor. Today, the Bilbao's have governed the municipality for a collective span of over thirty years.

When the Americans landed in Negros during World War II, Hinoba-an became a historical point of entry by the combined U.S. and Philippine Commonwealth military forces. Col. Salvador Abcede, district commander of the 7th military district, established his island headquarters in this town during the Japanese occupation.

Col. Jesús A. Villamor, aboard submarine USS Gudgeon (SS-211), landed at Ubong Point and occupied Ubong Cave as command post supply food and arms to guerillas.

After Liberation, Hinoba-an was rehabilitated by some of its pioneering residents. More settlements were established, schools were built, trails developed for the people's convenience in going to places and in transporting their local produce to nearby towns and villages. There was also a huge influx of Cebuano-speaking people during this time.

Hinoba-an is politically subdivided into 13 barangays. Each barangay consists of puroks and some have sitios.
