Cephalotes olmecus is an extinct species of arboreal ant of the genus Cephalotes known only from Mexican amber inclusions.

[1] Cephalotes olmecus was first described in 1999 from two Chiapas amber fossil inclusions of respectively a worker and a dwarf soldier ant.

[2] Maria de Andrade, who described the species, placed C. olmecus in the grandinosus clade in which it forms a subclade with fossil species Cephalotes maya and extant species Cephalotes foliaceus.

[2] The specific epithet olmecus is in reference to the Olmecs of Mexico.
