Poblana is a genus of Neotropical silversides that are endemic to Mexico, with each of the four threatened species restricted to a single Oriental Basin maar lake.

They are small fish that do not surpass 8 cm (3 in) in standard length.

[1] FishBase recognizes four species in this genus,[2] although genetic differences between them are very limited and some regard all as subspecies of P.

[3] Poblana is sometimes included in Chirostoma instead of being regarded a separate genus.
