Pirro leaves. Andromaca decides that, before she dies, she will make Pirro swear that Astianatte will be spared. Ermione, accompanied by Fenicio and Cleone, appears and insults Andromaca, who forgives her and departs. She asks Fenicio to tell Pirro that she still loves him, even if he is planning to desert her (Aria: "Di, che vedesti piangere" / "Tell him that you have seen my tears"). He leaves, and Cleone tells Ermione that Pirro is not worthy of her. Ermione contemplates suicide (Aria: "Amata, l'amai" / "I was loved and loved him").
