The Ulvophyceae or Ulvophytes are class of green algae, distinguished mainly on the basis of ultrastructural morphology. The sea lettuce, Ulva, belongs here. Other well-known members include Ulothrix , Acetabularia, and Caulerpa.

The Ulvophytes are diverse in their morphology and their habitat. Most are seaweeds such as those listed above. Others, such as Cladophora , Rhizoclonium and Pithophora live in fresh water and in some areas are considered weeds.
