El '''Nitratnitrat de plata''', és un compost químic de fórmula química [[plata|Ag]][[NitrògenNitrogen|N]][[OxígenOxigen|O]]<sub>3</sub>. Aquest compost és precursor de molts d'altres compostos com els que s'usen en la [[fotografia]]. Comparativament és menys sensible a la llum que els [[halid]]s de plata.
