The Pio Albergo Trivulzio, formally Azienda di servizi alla persona Istituti Milanesi Martinitt e Stelline e Pio Albergo Trivulzio, commonly referred to as Baggina, is an ancient retirement home and hospital in Milan, Italy.

In 1766, the Milanese aristocrat Tolomeo Trivulzio, at his death, devolved his belongings to the foundation of a shelter for the "poor old", to be housed in his own palace in the Verziere district (Via della Signora).

In the early 20th century the Trivulzio was relocated on the road connecting Milan to Baggio, and was thereafter nicknamed "the Baggina".

In 1992, the Trivulzio received much media attention as a consequence of the Tangentopoli political scandal, as its president Mario Chiesa was the first politician to be arrested in the Mani Pulite trial.

[2] Singer-songwriter Fabrizio De André mentioned "Il poeta della Baggina" ("The poet from the Baggina") in his song La domenica delle salme, included in 1990's album Le Nuvole.
