{{Multiple issues| {{More citations needed|date=July 2025}} {{No footnotes|date=July 2025}} }} [[File:Piani di Castelluccio June 2016.jpg|thumb|300px|Lentil and poppy blooming on Piani di Castelluccio.]] [[File:Monti Sibillini.jpg|thumb|300px|A summer view of the Monti Sibillini.]] The '''Sibillini Mountains''', or Sibylline Mountains ([[Italian language|Italian]]: ''Monti Sibillini'') are one of the major mountain groups in the [[Italian Peninsula]], and part of the [[Apennine Mountains|Apennines]] range. Most of the peaks are over {{convert|2000|m|ft|abbr=on}}; the highest is [[Monte Vettore]] at {{convert|2476|m|ft|abbr=on}}.
Since 1993 the area has been part of the [[Parco Nazionale dei Monti Sibillini]] (Sibillini Mountains National Park).
The present-day landscape morphology, predominantly U-shaped valleys and glacial depressions, is due to the action of [[glacier]]s during the [[Quaternary]] period.

The small [[Lago di Pilato]] within a deep U-shaped valley below Monte Vettore, is home to a [[crustacean]] [[endemic (ecology)|endemic]] to this location, ''[[Chirocephalus marchesonii]]''.
The area contains stands of [[beech]] scattered amongst open subalpine grasslands and meadows maintained by the grazing of sheep.
