Brunswick Square is a 1.5-acre (0.61 ha) privately owned public garden with residential streets along three of its sides, in the English city of Gloucester.

[1] The square dates back to the Roman era when it was known as the Gaudy Green, which originated from the Latin term "Gaudium" which means to enjoy.

Archaeological excavations of the site have found a Roman graveyard to the north, next to the Chillingworth Mews housing estate, which is likely to have extended into the square.

A managing group to maintain the garden was also formed and is known as the Brunswick Square Central Lawn Association.

In the 1960s, the city council wanted to turn the square into a car park, however the deed of covenant signed in 1825 prevented this from happening.
