List of green seaweeds of the Cape Peninsula and False Bay

This is a list of green seaweeds recorded from the oceans bordering the Cape Peninsula in South Africa from Melkbosstrand on the West Coast to Cape Hangklip on the South Coast.

Green seaweed refers to thousands of species of macroscopic, multicellular, marine algae in the taxon Chlorophyta The marine ecology is unusually varied for an area of this size, as a result of the meeting of two major oceanic water masses near Cape Point, and the area extends into two coastal marine bioregions.

The ecology of the west or "Atlantic Seaboard" side of the Cape Peninsula is noticeably different in character and biodiversity to that of the east, or "False Bay" side.

[1] List ordering and taxonomy complies where possible with the current usage in Algaebase, and may differ from the cited source, as listed citations are primarily for range or existence of records for the region.

Sub-taxa within any given taxon are arranged alphabetically as a general rule.
