[3] On June 16, 1955, the town's name was changed from Sabani to Gabaldon in honor of the former provincial governor and Philippine Resident Commissioner Isauro Gabaldón.

During the latter half of the 19th century, Gabaldon was the site of the Sabani Estate, the largest hacienda in Nueva Ecija, which was then part of Laur.

[9] On June 16, 1955, the municipality's name was changed from Sabani to Gabaldon by virtue of Republic Act 1318, to honor former provincial governor and Philippine Resident Commissioner Isauro Gabaldón.

[26]Due to Gabaldon's proximity to the coastal town of Dingalan, Aurora and its scenic location in the valley, there are several ecological tourist spots found in the municipality, including the Dupinga Water Reservoir, the Sierra Madre, Cabangcalan Lake, and multiple waterfalls dotting the southeastern part of the Sierra Madre.

Numerous resorts are in the municipality, including the Ecopark located inside the Gabaldon campus of the Nueva Ecija University of Science and Technology.
