Sigmund Schining ein Ringeck (Sigmund ain Ringeck, Sigmund Amring, Sigmund Einring, Sigmund Schining) was a 14th- or 15th-century German fencing master. While the meaning of the surname "Schining" is uncertain, the suffix "ain Ringeck" may indicate that he came from the Rhineland region of south-western Germany. He is named in the text of his treatise as Schirmaister to one Duke Albrecht, Count Palatine of Rhine and Duke of Bavaria.
