Sunny Beach (Bulgarian: Слънчев бряг, Slǎnchev bryag, German: Sonnenstrand) is a resort on the Black Sea coast of Bulgaria, located approximately 35 km north of Burgas in Nesebar municipality, Burgas Province. It is the biggest and most popular holiday resort of the country, and is home to over 150 hotels with more than 70 000 beds. There are also 140 restaurants and numerous live music bars, pubs, nightclubs, discos, cafes.In recent years almost the whole hotel base has been renovated and several new luxurious hotels have been built as well as many spectacular apartment complexes.

Sunny Beach during the summer is a choice for vacation for thousands of tourists. The main strip of high-rise hotels backing onto the beach is several kilometres long and extends along a wide bay between Sveti Vlas and Nesebar.

The climate of the area is Mediterranean, explaining Sunny Beach's popularity with tourists since before the fall of communism. Since that time the resort's popularity has grown among German holidaymakers, who add to the already large numbers of Bulgarian and Russian visitors. More recently, Sunny Beach has begun to attract the attention of British and Scandinavian tourists, for whom it is a more affordable alternative to the established Mediterranean resorts.

Attractions for tourists include the beach, watersports, nightlife, and the nearby historical site of Nesebar. Sunny Beach is mainly popular among young people. The Golden Orpheus International Festival of Popular Song, the Decade of Symphonic Music, part of the International Folklore Festival, fashion-shows and various beach competitions are held there.
