Vrbnik (Verbenico, German: Vörbnick) is a village and a municipality on the east coast of the island of Krk.

Vrbnik is naturally separated from mainland Croatia by the Vinodol Channel, where the towns of Crikvenica and Novi Vinodolski can be observed across the sea.

Vrbnik has a long history of 900 years, it was an important Frankopan castle, and a Glagolitic and religious center.

Places of cultural significance include the Vitezić library, the Gothic Chapel of the Rosary and the Chapel of St. John in the Parish Church of the Assumption, and a collection of ancient manuscripts and Glagolitic manuscripts housed at the parish church.

Vrbnik also claims to contain the world's narrowest street — Ulica Klančić is about 40–50 cm (1.3–1.6 ft) wide.
