The Chiavarone Famiglia is the third most powerful Famiglia that is allied with the Vongola Famiglia. It is one of the largest Famiglias, with over 5,000 members in its ranks, though only a few of them have been named. It is currently being led by its 10th generation Boss, Dino. Dino was Reborn's previous pupil before Tsuna, and as a result of Reborn's training, is a capable Mafia Boss unless none of his subordinates are around him; in that case, he becomes extremely clumsy, although he is unaware of his own problem. Dino has single-handedly raised the Chiavarone Famiglia to a prominent position by fixing their finances.
Although the Chiavarone Famiglia has over 5,000 members, only a few of them have been named, those of which are the following:
- Dino (Current and Tenth Boss)
- Dino's Father (Previous and Ninth Boss)
- Brutus (anime-exclusive)
- Michael (manga-exclusive)
- In the original Japanese media, its name is written as Cavallone.
- In a recent Reborn! Famiglia popularity poll, the Chiavarone Famiglia ranked fourth.
