Crystal Palace Park is a large park in south-east London, Grade II* listed on the Register of Historic Parks and Gardens. It was laid out in the 1850s as a pleasure ground, centred around the re-location of The Crystal Palace -- the largest glass building of the time -- from central London to this area on the border of Kent and Surrey; the suburb that grew around the park is known by the same name.

The Crystal Palace was a cast iron and plate glass structure, originally built in Hyde Park, London, to house the Great Exhibition of 1851. The exhibition took place from 1 May to 15 October 1851, and more than 14,000 exhibitors from around the world gathered in its 990,000 square feet (92,000 m2) exhibition space to display examples of technology developed in the Industrial Revolution. Designed by Joseph Paxton, the Great Exhibition building was 1,851 feet (564 m) long, with an interior height of 128 feet (39 m), and was three times the size of St Paul's Cathedral.
