We consider nilmanifolds with left‐invariant complex structure and prove that small deformations of such structures are again left invariant if the Dolbeault‐cohomology of the nilmanifold can be calculated using left‐invariant forms. By a result of Console and Fino this is generically the case. Our main tool is an analogue of Dolbeault‐cohomology for Lie‐algebras with complex structure.
