The mol­ecular structure of the title compound, [Al(CH3)2(C22H26NO)], displays a monomer with the AlIII atom in a distorted tetra­hedral environment defined by two methyl groups and the N and O atoms of the chelating ketiminate anion. The O—Al—N bite angle of the chelating ligand is 94.14 (9)°. The O—C—C—C—N backbone of the ligand is nearly coplanar (r.m.s. deviation = 0.029 Å) and the Al atom deviates significantly from the mean plane by 0.525 (3) Å. In the crystal, weak inter­molecular C—H⋯O inter­actions are observed.
