Pinus radiata, family Pinaceae, the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico (Guadalupe Island and Cedros island).

Pinus radiata is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses. Its silviculture is highly developed, and is built on a firm foundation of over a century of research, observation and practice. Radiata pine is often considered a model for growers of other plantation species. It is the most widely planted pine in the world, valued for rapid growth and desirable lumber and pulp qualities.

Although Pinus radiata is extensively cultivated as a plantation timber in many temperate parts of the world, it faces serious threats in its natural range.
