The first record and distribution of the bigheaded ant,\ Pheidole megacephala\ (Fabricius 1793) in the Gal\ápagos Islands are reported. Major and minor workers have been collected in the towns of Puerto Baquerizo Moreno (San Crist\óbal Island), Puerto Ayora (Santa Cruz Island), Puerto Villamil (Isabela Island) and in the highlands of San Crist\óbal. Field surveys and a revision of the Formicidae collection in the Invertebrates collection at the Charles Darwin Research Station (ICCDRS), California Academy of Sciences (CAS) and Royal Belgian Institute of Natural Sciences (RBINS) suggest that this species reached the Gal\ápagos Archipelago within the last seven years. The potential impact on native fauna of\ P. megacephala\ is discussed and appropriate measures to control and stop the spread of this species are mentioned.
