Psittacomimus (meaning "Psittacus imitator") is an extinct genus of psittacopedid bird from the Early Eocene London Clay Formation of Essex, United Kingdom.

[1] The holotype specimen, NMS.Z.2021.40.38, was discovered in 1991 by Michael Daniels in layers of the London Clay Formation (Walton Member), dated to the early Ypresian, which is located near Walton-on-the-Naze in Essex, England.

[1] The fossil material, particularly the nearly-complete skull, closely resembles bones of the contemporary related Parapsittacopes.

[1] A preliminary description of the fossil material was published by German paleontologist Gerald Mayr and Michael Daniels in 1998.

In 2022, Gerald Mayr and British zoologist Andrew C. Kitchener described Psittacomimus eos, a new genus and species of psittacopedid, based on these fossil remains.
