Essexella is an extinct genus of cnidarian known from Late Carboniferous fossils; it contains a single species, E. asherae.

It is one of the most recurrent organisms in the Mazon Creek fossil beds of Illinois;[1] in the Essex biota of Mazon Creek, it consists of 42% of all fossil finds.

[2] Essexella was originally described as a jellyfish,[3] but was recently redescribed as a sea anemone.

Essexella may have produced the common trace fossil Conostichus.
