The Dilkusha Bhulbhulaiya Garden Tower () is a historic garden tower located within the former Dilkusha Garden in Dhaka, Bangladesh. The site, originally developed in the 19th century by the Nawab family of Dhaka, featured a distinctive labyrinth or bhulbhulaiya of trees planted around the central tower. It served as a leisure and recreation spot where the Nawab family and guests played hide-and-seek.
The Dilkusha Garden was purchased in 1866 by Khwaja Abdul Ghani from a European owner, E. F. Smith. The Nawab commissioned the development of the garden house as a residence and leisure retreat for his family, particularly for his son, Khwaja Ahsanullah. Within the estate grounds, a central tower was erected and encircled by trees planted in concentric patterns to form a maze.
Today, little remains of the original maze or the tower. The tower's exact remnants are believed to be lost or buried under later constructions.
