2,6-Dimethylpiperidines are chemical compounds with the formula C5H8(CH3)2NH.

Three stereoisomers exist: the achiral (R,S)-isomer and the chiral (R,R)/(S,S) enantiomeric pair.

Dimethylpiperidines are derivatives of the heterocycle piperidine, wherein two hydrogen atoms are replaced by methyl groups.

The (R,S)-isomer exists largely in the chair conformation with equatorial methyl groups.

The (R,R)/(S,S)-isomers are attractive chiral secondary amine building blocks.
