Thiazyl trifluoride is a chemical compound of nitrogen, sulfur, and fluorine, having the formula NSF₃. It exists as a stable, colourless gas, and is an important precursor to other sulfur-nitrogen-fluorine compounds. It has tetrahedral molecular geometry around the sulfur atom, and is regarded to be a prime example of a compound that has a sulfur-nitrogen triple bond.

NSF₃ can be synthesised by the fluorination of thiazyl fluoride, NSF, with silver(II) fluoride, AgF₂:

or by the oxidative decomposition of FC(O)NSF₂ by silver(II) fluoride.:

It is also a product of the oxidation of ammonia by S
2F
10.

NSF₃ reacts with carbonyl fluoride (COF₂) in the presence of hydrogen fluoride to form pentafluorosulfanyl isocyanate (SF₅NCO).
