Pilgerina is a monotypic genus of flowering plants belonging to the family Santalaceae.

There are ten known subpopulations, in the former provinces of Antsiranana, Fianarantsoa, Toamasina and Toliara.

[1] The species is found in dry, subarid, humid, subhumid, and littoral forests between sea level and 1,499 meters elevation.

The three unprotected populations are threatened by continuing deforestation from mining, wildfire, and logging.

[1] The genus name of Pilgerina is in honour of Robert Knud Friedrich Pilger (1876–1953), a German botanist, who specialised in the study of conifers.
