Krk (Italian Veglia, German: Vegl; Latin Curicta) is a Croatian island in the northern Adriatic Sea, located near Rijeka in the Bay of Kvarner and part of the Primorje-Gorski Kotar county.

Krk is, together with Cres, the largest Adriatic island, with an area of 405.78 km², and also the most populous one, with numerous towns and villages totalling 17,860 (2001). Although recent student surveys pointed that Cres is the largest Croatian island, most recent official data show they are the same size.
