Swiftia rosea is a species of gorgonian-type octocoral in the family Plexauridae.

The polyps are in two rows on the thicker branches but near the tips they are closer together and more disordered.

[2] This sea fan resembles the closely related but rather less common Swiftia pallida, but is more densely branched.

[3] Swiftia rosea is native to the northeastern Atlantic Ocean including Scandinavia, Great Britain and Ireland.

[1] This sea fan also occurs in deep water on the continental shelf off the Atlantic coast of North America.
