The Thiruvananthapuram Zoo (also known as Trivandrum Zoo) is located in the city of Thiruvananthapuram, the capital of Kerala, India. It occupies 55 acres (22 ha) of woodland, lakes, and lawns.The Thiruvananthapuram Zoo was established by the Maharaja of Travancore in 1857 as an annex to the Napier Museum.

The zoo was originally built with the typical iron-barred cages prevalent at the time, and was designed for recreational purposes, but with increased loss of forest and wildlife due to human development, the goal of the Zoo has changed from recreation to conservation.A modernization project started in 1995 aims to gradually replace the old enclosures with spacious naturalistic enclosures. The state government of Kerala is undertaking this renovation with financial and technical help from the Central Zoo Authority.
