Burnhamia is an extinct genus of devil ray from the Paleogene period.

[1] Due to superficial similarities, some species were originally mistaken for Cownose rays and placed in the genus Rhinoptera.

There are several species attributed to this genus but their relation to each other is still unresolved.

Some have proposed the type species B. daviesi arises in the late Paleocene and persists until the middle Eocene giving rise to the similar genus Eoplinthicus with an earlier offshoot leading to smaller and less ornamented species in the lower Eocene, namely B.

[3] A Ypresian species, B. nessovi, known from a singular site in Kazakhstan was tentatively ascribed to the genus, though more material may show it warrant its own.
