Promicroceras is an extinct ammonite genus from the upper Sinemurian (Lower Jurassic)[1] of Europe, named by Leonard Spath in 1925. Promicroceras is included in the family Eoderoceratidae, which is part of the ammonitid superfamily Eoderoceratoidea.

Shells are evolute with an open umbilicus; strongly ribbed, ribs flattened on the venter, and with small spines without distinct tubercles.
