Velebit (pronounced [v̞ɛlɛ̌bit]; Latin: Mons Baebius; Italian: Alpi Bebie) is the largest, though not the highest, mountain range in Croatia.

Its highest peak is the Vaganski vrh at 1,757 m.[2] Major mountain passes on Velebit include the aforementioned Vratnik or Senjsko bilo at 694 m.a.s.l.,[2] where the Josephina connects Senj with Josipdol; Oštarijska vrata at 928 m.a.s.l.

[6] In the categorization of 113 of the highest points of Croatia by professor Vladimir Volenec, first published in 1990 and revised in 2015, there are 76 peaks from the Velebit.

A kind of leech was discovered in the pothole, which has been ascertained to represent a new species, genus and family; it has been named Erpobdella mestrovi.

List of potholes on Velebit deeper than 500 m: It is also home to Degenia velebitica, an endemic and protected species of plant in the mustard family discovered in 1907 by the Hungarian botanist Árpád von Degen.

In the Republic of Venice, Velebit was known as Montagna della Morlacca ("Mountain of the Morlach"), named after the Morlachs, an originally Romance ethnic group that eventually got assimilated into the local Croatian population, a generally socio-cultural and professional segment of the Slavic-speaking population rather than a Romance-speaking ethnicity.
