Arcella is a genus of testate amoebae or Arcellinida, usually found in freshwaters and mosses, and rarely in soils. A key characteristic of Arcella is the circular test with a hole on its center from where finger-like pseudopods emerge. It is one of the largest testacean genera.

Arcella is the name of a district in Padua, located close to the Milan-Venice railway, north-east of the station.
