Joinery is a part of woodworking that involves joining together pieces of wood, to create furniture, structures, toys, and other items. Some wood joints employ fasteners, bindings, or adhesives, while others use only wood elements.

Joinery used to build a house is different from that used to make puzzle toys, although some concepts overlap.
