(Serbo-Croatian Bakar), a royal free town of Croatia-Slavonia, Hungary; situated in the county of ModrusFiume, 7 m. S.E. of Fiume, on a small bay of the Adriatic Sea. Pop. (1900) 1870. The Hungarian state railway from Zakany and Agram terminates 22 m. from Buccari. The harbour, though sometimes dangerous to approach, affords good anchorage to small vessels. Owing to competition from Fiume, Buccari lost. the greater part of its trade during the 19th century. The staple industry is boatbuilding, and there is an active coasting trade in fish, wine, wood and coal. The tunny-fishery is of some importance. In the neighbourhood of the town is the old castle of Buccarica, and farther south the flourishing little port of Porto Re or Kraljevica.
