Pinus elliottii, commonly known as the slash pine, is a pine native to the southeastern United States, from southern South Carolina west to southeastern Louisiana, and south to the Florida Keys.

It is fast-growing, but not very long-lived by pine standards (to 200 years), and prefers humid climates and moist soils.
