Claudius Julius Ecclesius Dynamius (Latin: Claudius Iulius Ecclesius Dynamius)^[1] was a Roman senator during the late 5th-century who became consul in 488 and Urban prefect of Rome in 490 under Theodoric.^[2]

Ecclesius is known to have issued an edict, de fraudibus molendinariorum,^[1] which outlines the proper use of mills near Janiculum. He had public scales prepared in order to weigh the sacks of flour before and after the milling operation and fixes the millers' wages to three nummi per bushel.
