Pinus taeda, commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from central Texas east to Florida, and north to Delaware and southern New Jersey. The wood industry classifies the species as a southern yellow pine. U.S. Forest Service surveys found that loblolly pine is the second most common species of tree in the United States, after red maple. For its timber, the pine species is regarded as the most commercially important tree in Southeastern US.

The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas.

Loblolly pine is the first among over 100 species of Pinus to have its complete genome sequenced. As of March 2014 it is the organism having the largest sequenced genome size. Its genome with 20.15 billion base pairs is seven times larger than that of humans.
