Valencia was originally named Ermita, which means "a secluded place", due to its being a refuge from marauding Muslim pirates. In 1856, it was renamed Nueva Valencia by Spanish colonizers, in honor of its parish priest Father Matias Villamayor from Valencia, Spain. He also had a fountain brought over from his aforementioned hometown, which currently sits in front of the Town Hall.

In 1920, it was renamed Luzuriaga (often times misspelt as Luzurriaga) in honour of Don Carlos Ruíz de Luzuriaga, a delegate from Negros island to the Philippine Legislature who promised town officials he would work hard to help improve the town. The town reverted to Valencia in 1948, by virtue of Republic Act 252.

During World War II, Malabo was the headquarters of the Free Government and resistance movement in Negros Oriental.

The economy of Valencia is largely based on agriculture. Major products include abaca, copra, corn, flowers, vegetables, root crops, and exotic fruits such as lanzones and rambutan.

The municipality is also the site of a geothermal power station operated by the Energy Development Corporation. It generates electricity that supplies the needs of Negros, Panay, and parts of Cebu. The municipal government receives royalties from the power station.

Valencia, specifically, has a 20-megawatt Palinpinon 2 Geothermal Optimization Project in Sitio Nasuji, Barangay Puhagan, 35 kilometers from Dumaguete. The ₱1.74-billion geothermal optimization (expansion) project, funded the Development Bank of the Philippines (DBP) is part of EDC's 192-MW Southern Negros Geothermal Production Field that supplies the power needs of 8 provinces in Negros, Panay, Guimaras and Cebu Islands. Valencia's 192-MW Palinpinon I and II geothermal field ranks 4th in installed capacity nationwide. The Palinpinon field contributed $457.8 million in 2004 foreign exchange savings for 2004, and also generated $267 million savings from January to July, 2008.

Because Palinpinon is such a big source of geothermal energy, Gloria Macapagal Arroyo said it received P 250 million in royalties, applied for livelihood, education, related projects, and also for the 50% subsidy on Valencia electric bills consumers. Many residents also work in the nearby city of Dumaguete.

The Filipino-Japanese Amity Memorial Shrine is located in Valencia. It stands at the foot of Mount Talinis and marks the spot where the combined Filipino and American troops including the Negrosanon guerrilla units fought the Japanese Imperial Army toward the end of World War II.
