'''Nitrik oksida''' ([[nitrogen oksida]]<ref>[http://old.iupac.org/publications/books/rbook/Red_Book_2005.pdf PDF]</ref> atau nitrogen monoksida) merupakan sebatian kimia gas dengan formula kimia NO dan merupakan salah satu daripada [[nitrogen oksida|oksida-oksida nitrogen]]. Sebatian ini juga merupakan [[radikal bebas]] dan boleh diwakili dengan formula kimia ·NO.

Nitrik oksida boleh terhasil melalui [[kilat]] dalam ribut petir dan dalam proses pembakaran. Selain itu, nitrik oksida merupakan molekul pengisyaratan dalam proses fisiologi dan patologi mamalia, termasuk manusia.<ref>{{cite journal|pmid=10390607|year=1999|last1=Hou|first1=YC|last2=Janczuk|first2=A|last3=Wang|first3=PG|title=Current trends in the development of nitric oxide donors|volume=5|issue=6|pages=417–41|journal=Current Pharmaceutical Design}}</ref>

== Penghasilan ==

Dalam bidang komersial, nitrik oksida boleh dihasilkan melalui proses [[pengoksidaan]] [[ammonia]] dengan [[platinum]] sebagai [[mangkin]] pada suhu 750–900 °C (biasanya pada 850°C).

:4 NH<sub>3</sub> + 5 O<sub>2</sub> → 4 NO + 6 H<sub>2</sub>O

Dalam makmal pula, nitrik oksida boleh dihasilkan dengan mudah melalui proses penurunan [[asid nitrik]] dengan [[kuprum]].

:8 HNO<sub>3</sub> + 3 Cu → 3 Cu(NO<sub>3</sub>)<sub>2</sub> + 4 H<sub>2</sub>O + 2 NO
