"Non piangere, Liù" (Don't cry, Liù) is an aria sung by Calàf, the "Unknown Prince", in Act I of the Italian opera Turandot, by Giacomo Puccini. The lyrics were written by Giuseppe Adami and Renato Simoni. The scene takes place before the walls of the imperial palace. In the preceding aria (Signore, ascolta! - "My lord, listen!" ), Liù begs Calàf not to risk his life by playing a deadly game to marry Princess Turandot, and Calàf responds to her gently, asking her not to cry.
