Beerichthys ingens is an extinct prehistoric bony fish that was a member of the Ypresian London Clay fauna of lower Eocene England. It is known only from a series of incomplete skulls. When originally described in 1966, B. ingens was placed in a monotypic family, "Beerichthyidae," within Iniomi. Later, more (also incomplete) skulls were studied by Colin Patterson, who determined that the fish was a louvar.
