Trentepohlia is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae, living free on terrestrial supports such as tree trunks and wet rocks or symbiotically in lichens.

[2] The filaments of Trentepohlia have a strong orange colour (photograph at right) caused by the presence of large quantities of carotenoid pigments which mask the green of the chlorophyll.

[7] The genus was circumscribed by Carl Friedrich Philipp von Martius in Fl.

The genus name of Trentepohlia is in honour of Johann Friedrich Trentepohl (1748–1806), who was a German clergyman and botanist.
