Fluorine azide or triazadienyl fluoride is a yellow green gas composed of nitrogen and fluorine with formula FN₃. Its properties resemble those of ClN₃, BrN₃, and IN₃. The bond between the fluorine atom and the nitrogen is very weak, leading to this substance being very unstable and prone to explosion. Calculations show the F–N–N angle to be around 102° with a straight line of 3 nitrogen atoms.

The gas boils at –30° and melts at –139 °C.

It was first made by John F. Haller in 1942.
