C. B. Moore, or Clarence Bloomfield Moore, was an influential American archaeologist known for his extensive fieldwork and excavations of Native American sites in the southeastern United States during the late 19th and early 20th centuries. His work significantly contributed to the understanding of prehistoric cultures, including the Ancestral Puebloans (often referred to as the Anasazi), as he sought to uncover their lifestyles and cultural practices through archaeological investigation.
