The Puente Formation is a geologic formation in California. It preserves fossils dating back to the middle to upper Miocene epoch of the Neogene period, most of which were deposited in a deepwater environment. Owing to its depositional environment, it is one of the very few geologic formations to preserve articulated specimens of fossilized deep-sea anglerfish.
As its name suggests, it primarily outcrops in the Puente Hills.
