Ussuria is a genus of Lower Triassic ammonites with a smooth, involute discoidal shell with submonophyllic sutures, belonging to the ceratitid family Ussuriidae.
Ussuria has been found in Russia in Siberia (original discovery), China, Oman, and Idaho in the United States.
Ussuria somewhat resembles Sturia, commonly placed in the Ptychitidae.
