This review highlights archaeological investigations of precontact and historic house sites in Polynesia, a region noted for its diversity of chiefdoms in terms of scale and elaboration. Anthropological and historical perceptions of the Polynesian household have shifted over time, influencing the ways in which the household has been defined in archaeology. Early research emphasized houses as a unit of study within settlement pattern archaeology and as a means of delineating formal variability between sites and communities. Current studies stress a more holistic view of the household as a nexus of economic, social, and ritual activities. Diverse theoretical perspectives, such as the analytical concept of house societies, feminist archaeologies, landscape approaches, and agent-based models, have led to new archaeological approaches engaged with both the material and the nonmaterial aspects of the house and, in particular, how social relations structure the household. Current prominent themes include functional identification of house sites, understanding social variability, articulation of the household with the community, and comparative analyses of social complexity.
