Bredyia is an ammonite genus from the lower part of the Middle Jurassic, found in Europe and North America.
Bredyia is a member of the Hammatoceratidae, a family which comprises part of the Hildoceratoidea. Its shell is involute, strongly ribbed, with a small umbilicus. Whorls are strongly embracing; ribs thick, radially straight on the sides, curves forward on the venter but do not meet. The sides or flanks are outwardly bowed. The venter has a narrow keel and may be fastigate, like a gable roof.
