L''''òxid de dinitrogen''' (també conegut com a '''gas del riure''' i antigament anomenant '''òxid nitrós''')<ref name=europapress/> és un [[compost químic]] binari de nitrogen i oxigen de [[fórmula química]] <chem>N2O</chem>. A [[temperatura]] ambient és un [[gas]] no [[inflamable]], de punt d’ebullició -88,5 °C i punt de fusió -90,9 °C, incolor i totalment inert, amb una [[olor]] agradable, que té uns efectes totalment innocus per a l'organisme i un gust lleugerament [[gust dolç|dolç]].
