Yes. Every living great ape species—chimpanzees, bonobos, gorillas, and orangutans—is listed as Endangered or Critically Endangered on the IUCN Red List of Threatened Species.
According to the IUCN SSC Primate Specialist Group, many taxa are Critically Endangered (including all orangutans, western lowland and Cross River gorillas, and western chimpanzees), while others such as bonobos, most chimpanzee subspecies, and mountain gorillas are Endangered. Main threats include habitat loss and fragmentation, hunting, disease, and climate pressure; mountain gorillas are a rare case where numbers have been increasing under intensive protection.
