Riserva naturale Badia Prataglia, Nature reserve in Tuscany and Emilia-Romagna, Italy.

Riserva naturale Badia Prataglia is a protected forest area located in the mountains between Tuscany and Emilia-Romagna, straddling two provinces and spanning a large territory. The landscape consists mainly of beech and silver fir forests interspersed with streams, steep slopes, and a network of walking paths for visitors to explore.

In 1380, the Florentine Republic took control of the forest from the Guidi family, shifting political power in the region. The Florentines later handed management to the Opera del Duomo of Santa Maria Novella, where it remained under their authority for centuries.

The reserve lies in the Casentinesi forests, split between a Romagna part called Foresta della Lama and a Tuscan part called Foresta di Fiume d'Isola. Its woods were once managed for the Opera del Duomo of Santa Maria Novella, and place names such as Siepe dell'Orso and Pian dell'Orso recall the brown bear hunted out in the early 1800s.

The reserve lies within the Foreste Casentinesi national park, with the Tuscan part known as Foresta di Fiume d'Isola and the Romagna part as Foresta della Lama. It is managed by the Carabinieri Biodiversity unit based in Pratovecchio, Arezzo. Paths cross beech and silver fir woods on mountain slopes, so plan for climbs and check conditions before setting out.

The reserve's beech and silver fir woods were long exploited for railway sleepers and charcoal: from 1900 the S.A.I.F. company worked the forest intensively until the Italian state bought it on 2 March 1914. Brown bears were hunted out in the early 1800s, but their memory survives in place names such as Siepe dell'Orso and Pian dell'Orso.
