Tragidion coquus is a species of longhorn beetle in the family Cerambycidae.

[1][2] Individuals of this species have a black head and pronotum, with highly variable amounts of orange on the elytra, ranging from almost completely orange to black.

[3] Tragidion coquus was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae.

The specific epithet is sometimes misspelled as "coquum", but it is a noun[4] and must retain the spelling "coquus" under the ICZN.
