Pinus radiata (syn. Pinus insignis), the Monterey pine, insignis pine or radiata pine, is a species of pine.

P. radiata is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses and valued for rapid growth, as well as desirable lumber and pulp qualities.

Although P. radiata is extensively cultivated as a plantation timber in many temperate parts of the world, it faces serious threats in its natural range, due to the introduction of a fungal parasite, the pine pitch canker.

P. radiata is a coniferous evergreen tree growing to 15–30 m tall in the wild, but up to 60 m in cultivation in optimum conditions.
