Obzor is a small town and seaside resort on the Black Sea coast of Bulgaria. It is part of Nesebar Municipality, Burgas Province.

The Thracian and ancient Greek name of Obzor was Naulochos. It was a small port on the coast of Thrace, a colony of Mesembria. The ancient Romans named it Templum Iovis (Temple of Jupiter); Pliny called it Tetranaulochus. During the Ottoman rule of Bulgaria, it was known as Gözeken. The modern name was introduced in 1936; Obzor obtained town privileges on 9 September 1984.

The 2200-m-long Kaleto eco path connects the northwestern outskirts of Obzor with the remains of a medieval fortress. Visitors can see a 10-m-high waterfall and a mineral spring along the trail.
