Marmarole is a mountain group of the Dolomites in Belluno, northern Italy. Located west of the Cadore Valley and north-east of the major peak of Antelao, it is known as a wild range, possibly the wildest of the entire Dolomites, due to the relative difficulty of climbing its peaks and its isolation from nearby valleys. Conversely, it is a popular destination for experienced hikers and alpinists.

The highest peak of the Marmarole is the Cimon del Froppa which reaches 2,932 m.

According to SOIUSA, the Marmarole are an alpine group with the following classification:

Big part = Eastern Alps Large sector = South-Eastern Alps Section = Dolomites Subsection = Sesto, Braies and Ampezzo Dolomites Supergroup = Cadore Dolomites Group = Marmarole Group Code = II / C-31.I-E.21

The group is then divided into three subgroups:

Bel Pra subgroup (also called Western Marmarole) Subgroup of Central Marmarole Subgroup of Ciastelin (also called Oriental Marmarole)
