Riserva naturale Monte Velino, State nature reserve in Province of L'Aquila, Italy.

The Riserva naturale Monte Velino is an oriented nature reserve of 3,550 hectares on the Monte Velino massif, shared by Magliano de' Marsi and Massa d'Albe in Abruzzo and a part of Borgorose in Lazio. It borders the Montagne della Duchessa reserve to the north and lies within the Sirente-Velino regional park. Its slopes hold gentian, the Marsican iris, red lily, rare peonies and orchids.

The reserve was created by Ministerial Decree no. 427 of 21 July 1987, after protection efforts in the area had been pursued since the mid-1960s. It followed the establishment of protected areas on Monte Sirente, the chain's other mountain, and was placed within the Sirente-Velino regional nature park. It continues the adjacent Montagne della Duchessa reserve in the province of Rieti and is managed by the Carabinieri biodiversity and parks office of Castel di Sangro.

The museum of man and nature (museo dell'uomo e della natura) has its seat at Magliano de' Marsi and is devoted to the biodiversity of the reserve. Its exhibits cover the protected area's flora and fauna, from the marsican iris and rare peonies to the Apennine wolf and the griffon vulture reintroduced in the 1990s.

Access is available from Rosciolo de' Marsi or Forme via the A25 highway, though some trails may be closed from February through August. Visitors should check current access conditions ahead of time and bring sturdy footwear.

The reserve hosts an Oasi del cervo project launched in the 1990s to repopulate deer across the Sirente-Velino chain. The imperial raven was reintroduced here in 1995 by the State Forestry Corps, and griffon vultures were also brought back during the 1990s.
