Adelia, o La figlia dell'arciere (Adelia, or The Archer's Daughter) is an opera in three acts by Gaetano Donizetti. The Italian libretto was written partly by Felice Romani (Acts 1 and 2) and by Girolamo Maria Marini (Act 3), a part-time poet who had achieved notability the previous year with Otto Nicolai's Il templario.
