Zeliszkella is a genus of trilobite in the order Phacopida, with species of average size.

Species are known from the Middle and Upper Ordovician and have been found in the Czech Republic, France, Morocco, Portugal and Spain.

The large mosaic (schizochroal) eyes reach far backward.

The main body (or thorax) is composed of eleven segments.

The side lobes (pleurae) of the thorax curve stronger backward closer to the tail shield (or pygidium), their pointed tips longer than those of anterior pleurae.
