The David di Donatello Award for Best Screenplay (Italian: David di Donatello per la migliore sceneggiatura) was a film award presented by the Accademia del Cinema Italiano (ACI, Academy of Italian Cinema) to recognize outstanding screenwriting in a film released in Italy during the year preceding the ceremony. The award was presented annually from 1975 to 2016, when it was split between the Original and Adapted Screenplay categories.
Nominees and winners were selected via runoff voting by all the members of the Accademia.
