In algebraic geometry, Max Noether's theorem may refer to the results of Max Noether:

• Several closely related results of Max Noether on canonical curves
• AF+BG theorem, or Max Noether's fundamental theorem, a result on algebraic curves in the projective plane, on the residual sets of intersections
• Max Noether's theorem on curves lying on algebraic surfaces, which are hypersurfaces in P³, or more generally complete intersections
• Noether's theorem on rationality for surfaces
• Max Noether theorem on the generation of the Cremona group by quadratic transformations

• Noether's theorem, usually referring to a result derived from work of Max's daughter Emmy Noether
• Noether inequality
• Special divisor
• Hirzebruch–Riemann–Roch theorem
