Marcello and Rodolfo are trying to work, though they are primarily talking about their girlfriends, who have left them and found wealthy lovers. Rodolfo has seen Musetta in a fine carriage and Marcello has seen Mimì dressed like a queen. The men both express their nostalgia (duet: ''O Mimì, tu più non torni''—"O Mimì, will you not return?"). Schaunard and Colline arrive with a very frugal dinner and all parody eating a plentiful banquet, dance together and sing, before Schaunard and Colline engage in a mock duel.

Musetta suddenly appears; Mimì, who took up with a wealthy viscount after leaving Rodolfo in the spring, has left her patron. Musetta found her that day in the street, severely weakened by her illness, and Mimì begged Musetta to bring her to Rodolfo. Mimì, haggard and pale, is assisted onto a bed. Briefly, she feels as though she is recovering. Musetta and Marcello leave to sell Musetta's earrings in order to buy medicine, and Colline leaves to pawn his overcoat (''Vecchia zimarra''—"Old coat"). Schaunard leaves with Colline to give Mimì and Rodolfo some time together. Mimì tells Rodolfo that her love for him is her whole life (aria/duet, Mimì and Rodolfo: ''Sono andati?''—"Have they gone?").

To Mimì's delight, Rodolfo presents her with the pink bonnet he bought her, which he has kept as a souvenir of their love. They remember past happiness and their first meeting—the candles, the lost key (Mimi playfully confesses that she had figured out that Rodolfo had pocketed it). Mimì is overwhelmed by a seizure of coughing. The others return, with a gift of a muff to warm Mimì's hands and a cordial to soothe her cough. Mimì gently thanks Rodolfo for the muff, which she believes is a present from him, reassures him that she is better, and falls asleep. Musetta prays. Schaunard discovers that Mimì has died. Rodolfo rushes to the bed, calling Mimì's name in anguish. He sobs helplessly as the curtain falls.
