Lalbagh Botanical Gardens or Lalbagh is an old botanical garden in Bengaluru, India. First planned and laid out during the rule of Hyder Ali and later adorned with unique plant species by his son Tipu Sultan, it was later managed under numerous British Superintendents before Indian Independence. It was responsible for the introduction and propagation of numerous ornamental plants as well as those of economic value.

It also served a social function as a park and recreational space, with a central glass house dating from 1890 which was used for flower shows. In modern times it hosts two flower shows coinciding with the week of Republic Day (26 January) and Independence Day (15 August). As an urban green space along with Cubbon Park, it is also home to numerous wild species of birds and other wildlife. The garden also has a lake adjoining a large rock on which a watchtower had been constructed during the reign of Kempegowda II.
