Joinery is the part of woodworking that involves the joining together of parts of wood to make wooden objects such as boxes, tools, houses, etc.

Two of the most common traditions of joinery are Chinese and European. Chinese in particular developed hundreds of types of joints and their furniture was often held together without glue or nails. There are also different types of joinery for different structures, for example the joinery used to build a house is different from that used to make puzzle toys, although elements overlap.

Some types of joints used include:

• tongue and groove
• dove tailing
• sliding dovetail
• mortise and tenon
• scarf joint
