We present a facile solution‐phase method for the synthesis of Cu
2
S microcrystals with rod‐like morphologies by the reaction of sulfur with three‐dimensional substrate copper foam in a mixed solvent of ethylene glycol and deionized water. The lengths of Cu
2
S microrods are between 80 and 150 μm and the diameter is among 3 to 8 μm. Monodisperse Cu
2
S microrods self‐assemble into echinus structure. The samples were characterized by X‐ray powder diffraction and scanning electron microscopy. Energy dispersive X‐ray spectroscopy was further used to testifiy the purity of Cu
