Boulengerula fischeri is a species of caecilian in the family Herpelidae.

[1][3] The specific name fischeri honours Eberhard Fischer, a German botanist who has worked with Rwandan fauna and flora.

It lives in the soil,[1] occasionally on the ground under leaf litter or plant stems.

[5][6] If similar to other Boulengerula, it would be oviparous and have direct development (no free-living larvae).

The area of the type locality is now included in the Nyungwe Forest National Park.
