Codeine, or 3-methylmorphine, is an opioid of the morphinan class. Codeine and other molecules of this class contain a polycyclic core of three benzene rings fused in a zig-zag pattern called phenanthrene. A fourth nitrogen-containing ring is fused to the phenanthrene at R9 and R13 with the nitrogen member looking at R17 of the combined structure. This structure is called morphinan. Codeine (along with other morphinans) contains an ether bridge between two of its rings, connecting R4 and R5 through an oxygen group. It contains a hydroxy group (OH-) bound at R6 and a methyl group located on the nitrogen atom at R17.

On the same ring containing the hydroxy group, codeine contains a double bond which [[dihydrocodeine]] lacks. Codeine is closely related to morphine as both contain an oxygen group at R3, but this oxygen group in codeine is substituted by a methyl group (making a methoxy group). Codeine is analogous to the other morphinans including [[dihydrocodeine]], [[heroin]], [[ethylmorphine]], [[hydrocodone]], and [[oxycodone]].
