Bannerghatta Biological Park, also known as the Bannerghatta Zoo, is a zoological garden located in the city of Bengaluru. It was initially a small zoo and picnic corner within Bannerghatta National Park (BNP) which was started in 1974. The bifurcation of the Biological Park and the National Park took place in 2002. The Bannerghatta Biological Park covers a total area of 731.88 hectares and includes a zoo, safari park, butterfly park and rescue centre. The Zoo Authority of Karnataka, the University of Agricultural Sciences, Bangalore, and the Ashoka Trust for Research in Ecology and Environment (ATREE), Bangalore, are collaborating agencies. For the convenience of the general public, the Governing Council of Zoo Authority of Karnataka had decided to rename Bannerghatta Biological Park as 'Bengaluru Bannerghatta Biological Park' (BBBP).

The Chief Conservator of Forests in the Karnataka Forest Department, Shri Y.M.L Sharma, IFS and founder of Bannerghatta National Park, created a picnic corner within the Bannerghatta forest in 1971. The Bannerghatta National Park was officially created in 1974 for conserving the flora and fauna in the area. As a result of demands for providing recreational and wildlife tourism facilities to the visiting tourists, the idea came about for creating a mini zoo and a nature park by carving out a small portion out of the tourism zone inside the national park.

The lion safari was established in 1979, followed by the establishment of tiger safari in 1987. In 2000, a dedicated wildlife rescue and rehabilitation centre was established with the assistance of the Central Zoo Authority of India. In 2002, the Government of Karnataka created a dedicated organization, the Zoo Authority of Karnataka (ZAK) for the management zoos in the state. Following this, the Bannerghatta zoo, various safari units and rescue centres within the national park were pooled together to form the Bannerghatta Biological Park and brought under the jurisdiction of the Zoo Authority of Karnataka. In 2007, a Butterfly Park was established within the limits of the Biological Park.

The Bannerghatta Biological Park is located within the limits of Anekal Revenue Taluk in the Bangalore Urban District. The park is situated almost midway between the city center of Bengaluru and the Anekal town, at about 25 km from Vidhana Soudha and at about 20 km to the North West of Anekal town. It is connected to the city by an all weather road. It is situated at the distance of 4 km from Gottigere, which is the boundary of the Bruhat Bengaluru Mahanagara Palike (BBMP).

Currently, the Banneghatta Biological Park consists of the Bannerghatta Zoo, the Safari, the Butterfly Park and the Rescue and Rehabilitation centre.

The Bannerghatta Zoo was started as a picnic corner and was controlled by the Forest Department, Government of Karnataka, in the year 1971 in an area of 16.00 Ha. The zoo is saddled between the Champakadhama hill and Mirza hill in the Bannerghatta Sandal Reserve. Several species of mammals, reptiles and birds of both exotic and Indian origin are displayed in captivity. There are 1941 individual animals belonging to 94 different species. Most prominent and interesting ones are Thamin deer, Hog deer, King Cobra, Crocodiles, Himalayan black bear, panthers and various birds. In addition there is a Museum and an Auditorium for the visitors education. Present extent of Zoo area is 12 Ha and it is expanded by another 28.00 Ha. Eight new enclosures will be constructed in the expansion area.

The park offers safari excursions to observe the free range captive wildlife in immersive, naturalistic exhibits in the midst of the natural forests of Bannerghatta and Ragihalli Reserve Forest. The safari is jointly managed and monitored by Karnataka State Tourism Development Corporation (KSTDC) and BBP with a revenue sharing on a 50:50 basis between the two organizations. There are different types of transport such as bus, van etc. Each has one amount. KSTDC focuses on sales, revenue collection and physical monitoring of the buses whereas BBP fixes the fee for the visitors. The buses have a seating capacity of 30 people and other vehicles are also available to visitors in smaller groups. The visitors are only allowed inside the safari in these secured safari vehicles. The safari route passes through the picturesque hillock Mettubunde offering a panoramic view of the landscape consisting of broken hillocks chains and valleys with lush green forests.

In late September 2013, the safari was closed for weeks due to an outbreak of foot and mouth disease among the herbivorous animals.
