Fedomia is a genus of organisms resembling sea sponges from the Ediacaran Period.

[1] The organisms look like sacs, often connected and occasionally radiating from a central point, and are millimetres to centimetres in length.

Their surface is often patterned with a number of concave, star-shaped, spicule-like structures with six to eight points, with a diameter of 2–5 mm; these were probably flexible rather than rigid.
