Sulfur nitride may refer to a number of sulfur nitrogen compounds:

• pentasulfur hexanitride, S₅N₆
• tetrasulfur tetranitride, S₄N₄
• tetrasulfur dinitride, S₄N₂
• disulfur dinitride, S₂N₂
• polythiazyl, (SN)_x
• thiatetrazole, SN₄

Additionally, some unstable species are known:

• sulfur mononitride, SN, analogous to nitric oxide, NO
• disulfur mononitride, S₂N, analogous to nitrogen dioxide, NO₂.^[1]
• monosulfur dinitride, SN₂, analogous to nitrous oxide, N₂O
