{{Main|IUPAC nomenclature of organic chemistry#Amines and amides}}
The core {{chem2|\sC(\dO)\s(N)}} of amides is called the '''amide group''' (specifically, '''carboxamide group''').

In the usual nomenclature, one adds the term "amide" to the stem of the parent acid's name. For instance, the amide derived from [[acetic acid]] is named [[acetamide]] (CH<sub>3</sub>CONH<sub>2</sub>). IUPAC recommends [[ethanamide]], but this and related formal names are rarely encountered. When the amide is derived from a primary or secondary amine, the substituents on nitrogen are indicated first in the name. Thus, the amide formed from [[dimethylamine]] and [[acetic acid]] is ''N'',''N''-dimethylacetamide (CH<sub>3</sub>CONMe<sub>2</sub>, where Me = CH<sub>3</sub>). Usually even this name is simplified to [[dimethylacetamide]]. Cyclic amides are called [[lactam]]s; they are necessarily secondary or tertiary amides.<ref name=Fletcher /><ref>{{BlueBook2004|rec=66.1}} Full text (PDF) of Draft Rule P-66: [https://old.iupac.org/reports/provisional/abstract04/BB-prs310305/Chapter6-Sec66.pdf Amides, Imides, Hydrazides, Nitriles, Aldehydes, Their Chalcogen Analogues, and Derivatives]</ref>
