Maitansine (INN), or maytansine (USAN), is a cytotoxic agent. It inhibits the assembly of microtubules by binding to tubulin at the rhizoxin binding site. The maytansine binding site and binding mode has been characterized.

It is a macrolide of the ansamycin type and can be isolated from plants of the genus Maytenus.
