Gymnogyps amplus is an extinct species of large New World vulture in the family Cathartidae. The species was first described by Loye H. Miller (1911){{cite journal |last1=Miller |first1=Loye Holmes |title=Avifauna of the Pleistocene Cave Deposits of California |journal=Bulletin of the Department of Geology |date=1911 |volume=6 |issue=16 |pages=390–391 |url=https://biodiversitylibrary.org/page/43409048 |publisher=University of California Publications}} in 1911 from a partial tarsometatarsus{{cite news |date=26 October 2007 |first=Elisabeth|last= Nadin|title=Tracing the Roots of the California Condor |work=Caltech News|publisher=California Institute of Technology|url=http://www.caltech.edu/news/tracing-roots-california-condor-1341 |access-date=11 October 2015 }} recovered from Pleistocene cave deposits in Samwel Cave of northern California.{{cite journal |last1=Fisher |first1=H.

The species is the only condor species found in the La Brea Tar Pits' Pit 10, which fossils date to "a Holocene radiocarbon age of 9,000 years." The smaller, modern California condor may have evolved from G. amplus.
