Lessonia is a genus of large kelp native to the southern Pacific Ocean. It is distributed along the coasts of South America, New Zealand, Tasmania, and the Antarctic islands.[1]

This is one of two principal genera in kelp forests (the other is Macrocystis). In Chile, the preservation of Lessonia wild kelp is a crucial factor for the rocky shores. By harvesting these wild populations of Lessonia kelp, marine biologists are able to analyze the effects of kelp towards wildlife.[2]

Some species are of economic importance, such as Lessonia nigrescens, which is harvested for alginate.[3]
