Pachycondyla eocenica is an extinct species of ant in the formicid subfamily Ponerinae described from fossils found in Europe.

[1] Along with other well-preserved insect fossils, the P. eocenica specimens were collected from layers of the Lutetian Messel pit World Heritage Site.

The area is a preserved maar lake which initially formed approximately 47 million years ago as the result of volcanic explosions.

[2] At the time of description, the holotype specimen, number SMF MeI 10999, was preserved in the Senckenberg Research Station Messel fossil collections.

[3] The Pachycondyla eocenica holotype specimen is a partially preserved adult queen, which was fossilized as a lateral impression, missing portions of the legs and wings.
