Wood is, and always has been, one of the most common and versatile materials for creating structures and art. It is therefore also a ubiquitous element of the archaeological record. This discussion of the study of archaeological wood introduces a number of approaches to the analysis of these organic remains, including a brief overview of wood science, factors that impact the survival of wood materials, wood anatomy, and dendrochronology. These sections are intended to help archaeologists and other interested non-specialists prepare to encounter archaeological woods, and to understand the potential scientific data that these remains could contribute to our understanding of the human past. This is followed by additional approaches from the social sciences. The study of woodworking techniques and toolmarks, combined with ethnoarchaeology and experimental archaeology, can push wood analyses further. A combination of these approaches can help to create a more holistic view of humankind's relationship to wood.
