Douglas Fir or Pacific Coast Douglas Fir, is a timber of good strength and durability and is available in merchantable and clear grades. Large sections lend themselves to heavy constructional use, while smaller kiln dried, clear sections work well in both internal and external joinery applications.

There are two major varieties of timber, Coast Douglas Fir or Green Douglas Fir based on the Pacific coast and and Rocky Mountain Douglas Fir or Interior Douglas Fir.

The tree takes its English name from David Douglas, the Scottish botanist who first introduced it into cultivation. Other names for the timber include Oregon Pine, Pacific Douglas Fir.
