Rezovo (Bulgarian: Резово, pronounced [ˈrɛzovo]) is a village and seaside resort in southeastern Bulgaria, part of Tsarevo Municipality, Burgas Province, in the coastal Strandzha geographical region.

According to Austrian Wenzel von Brognard and other 18th-century western travellers, the river mouth at that place had a good wharf suitable as a storm and winter shelter.

However, the locals were forced to move inland because of persistent raids by Caucasian Laz pirates, settling during the 19th century in the Kladarsko Bardo area 10 kilometres to the west, also along the Rezovo River.

In 1903, the residents of Rezovo took an active part in the Bulgarian Ilinden-Preobrazhenie Uprising, seeking unification with their compatriots in the Principality of Bulgaria.

The population has gradually declined, however, but today Rezovo is a popular beach resort and a spot frequented by tourists because of its southeasternmost location.
