Phoberomys pattersoni is an extinct rodent that lived in the Orinoco River delta approximately 8 million years BP.

An almost complete skeleton of Phoberomys, discovered in Venezuela in 2000, has enabled researchers to reconstruct its size and probable lifestyle. It was 3 m long, with an additional 1.5 m tail, and probably weighed around 700 kilograms, making it the largest known rodent. Like many other rodents, Phoberomys was a herbivore with high-crowned premolars and molars.
