Munții Stânișoarei, Mountain range in northeastern Romania.

Munții Stânișoarei is a flysch mountain range in the Eastern Carpathians, stretching about 60 km northwest–southeast across Neamț and Suceava counties. Its main ridge is asymmetric, steeper on the west (19–20°) than on the east (14–15°), and only two peaks exceed 1,500 m: Bivolul (1,530 m) and Bâtca Comorii (1,513 m). The highest summits are built of resistant Cretaceous Ceahlău conglomerates.

The range belongs to the flysch unit of the Eastern Carpathians, built mainly of Ceahlău and Tarcău rocks: sandstones, conglomerates, marls and clay schists. Its present relief dates at least from the Sarmatian, when the Moldova-Bistrița interfluve level (556–750 m) persisted. In the Quaternary valleys cut 100–140 m deeper and slopes were reshaped by periglacial processes. The highest summits, including Bivolul (1,530 m), sit on resistant Cretaceous Ceahlău conglomerates.

The name Stânișoarei comes from pastoralism, the herding occupation practiced on the mountain meadows along the upper ridges. Calistrat Hogaș described the range and its monasteries in "Pe drumuri de Munte", and Mihail Sadoveanu set the tragedy of Vitoria Lipan from the novel Baltagul in these mountains. The area is also known for its monastic life and the many hermits who lived alone in the forests for centuries.

The range lies in Neamț and Suceava counties, bounded by the Puzdrea–Ostra corridor and the Brăteasa and Suha valleys to the northwest and by the Bistrița to the west and south. The Bistrița defiles at Izvorul Muntelui and Straja cut through Eocene Tarcău sandstone. The low saddle at Petru Vodă, about 900 m, is the main crossing point.

The name Stânișoarei comes from stână, the sheepfold, because the mountain pastures on the crests supported shepherding. The range belongs to the flysch unit of the Eastern Carpathians, built largely of Ceahlău and Tarcău sandstones, conglomerates and marls, not limestone. Vârful Bivolul, at 1,530 m, sits in the centre of a raised syncline holding a mass of Cretaceous Ceahlău conglomerate.
