"Vorticella" is a genus of protozoa, with over 100 known species. They are stalked inverted bell-shaped ciliates, placed among the peritrichs. Each cell has a separate stalk anchored onto the substrate, which contains a contracile fibril called a myoneme. When stimulated this shortens, causing the stalk to coil like a spring. "Vorticella" mainly live in freshwater ponds and streams - generally anywhere protists are plentiful.

Reproduction is by budding, where the cell undergoes longitudinal fission and only one daughter keeps the stalk. The free daughter becomes a telotroch, which swims until it finds suitable substrate to fix and develop its own stalk.

Other genera such as "Carchesium" resemble "Vorticella" but are branched or colonial.
