The Queen of Hearts or Dama Kupa (Bulgarian: „Дама Купа”) is a historic building and former hotel in the Black Sea resort town of Balchik, Dobrich Province, northeastern Bulgaria.

The Queen of Hearts was finished in 1871 and its architecture includes Neo-Baroque and Neo-Gothic features.

Its facade was constructed out of local white Balchik limestone, with lead elements incorporated for stability.

For some time, its name was the Silver Coast Hotel (Bulgarian: Сребрист бряг, Srebrist bryag), inspired by the nickname of the scenic Black Sea coastline between Balchik and Kavarna.

Allegedly, he who won a fortune in a cards game by betting on the queen of hearts and invested in a European-style hotel in the then bustling oriental port town of Balchik, only to lose the investment in another bet.
