Softwood refers to wood derived primarily from gymnosperm trees, especially conifers. It is distinguished from hardwood, which comes from angiosperm species. Softwoods are among the most widely used timber types in construction and industry due to their availability, relatively low cost, and favorable strength-to-weight ratio.

Physically, softwoods tend to be lighter and less dense than many hardwoods. They have a simpler cellular structure, dominated by tracheids, and often contain resin canals. They are typically easy to cut, nail, screw, and plane, and they respond well to gluing and finishing. Their mechanical properties vary by species but generally provide good stiffness and adequate strength for framing and general carpentry. Moisture changes can cause shrinkage, warping, and checking, so proper drying and moisture control are important. Most softwoods are less resistant to decay and insects than durable hardwoods; heartwood can be more durable than sapwood, and many softwoods are treated with preservatives for outdoor use.

Common softwood species include pine, spruce, fir, and sometimes cedar, larch, and Douglas fir. Typical products are dimensional lumber, plywood cores, decking, siding, and mass timber components, as well as pulp for paper production.

Environmental considerations: Softwood forests are often fast-growing and renewable, supporting sustainable forestry practices and certification schemes. Lifecycle impacts depend on forest management, transportation, and processing energy.
