Choiaella is an extinct genus of demosponge ranging from the Chengjiang lagerstatten until the Lower Silurian.[1]

It is closely related to the genera Choia and Allantospongia, which the Chengjiang fauna species C. radiata coexisted sympatrically with.

The species C. scotica is known from the Caradoc-aged fine sandstone of Wallace's Cast, Southern Uplands of Scotland.[1]

The Silurian species has not been formally named.[1]
