Smilax biltmoreana, common name Biltmore's carrionflower,[2] is a North American plant species native to the south-eastern United States.

It is concentrated in the Great Smoky Mountains but with outlying populations in Virginia, North and South Carolina, Tennessee, Kentucky, Georgia, Alabama, and northern Florida.

[1][3] The species epithet biltmoreana refers to the Biltmore Estate in Asheville, North Carolina, once owned by George Washington Vanderbilt.

Vanderbilt sponsored a significant number of botanical studies in the American Southeast in the late 19th and early 20th Centuries.
