Objectives Stable isotope analysis can provide crucial insight into the function and development of early state‐level societies on the north coast of Peru. Materials and Methods Multi‐tissue (bone collagen, tooth enamel, hair, nail, skin, and tendon) stable isotope analyses (carbon, nitrogen, sulfur, and strontium) were conducted for 13 individuals from the lower Virú Valley. Results Non‐seasonal changes in a predominantly C 4 ‐based terrestrial diet, with minimal inputs of marine foods were identified. One individual (Burial 5), however, had a stable isotope signature unlike any previously found on the north coast of Peru, indicating both a large contribution of C 3 ‐terrestrial resources to their diet and an 87 Sr/ 86 Sr value suggestive of highland residence during childhood. Discussion This research provides the first strong stable isotope evidence of a highland individual within a coastal burial in northern Peru, new insight into the ritual killing event at Huaca Santa Clara during the late middle horizon and supporting evidence of the importance of C 4 terrestrial resources to the developing Virú polity during the early intermediate period.
