Baccharis glutinosa is a species of flowering plant in the family Asteraceae known by the common names saltmarsh baccharis and Douglas' falsewillow.

The North American populations were for many years listed as a separate species, B. douglasii, but more recent studies suggest that the plants from the two continents are better regarded as one species.
