The Catalpa trees were felled in January after Cotswold District Council's tree experts branded them a health and safety risk.
But residents reacted with anger after seeing the square, named after the trees planted in the 1960s, and mounted a petition.
The lobbying has paid off and Pyrus chanticleer trees will be planted in their place in November.
The trees will be 4.5m when planted to give an immediate visual impact, and will reach a height of about 15m.
Cirencester Town Council has supported the scheme by offering to water the trees over the first two years.
Specialist watering tubes and metal guards will be installed to help the trees mature.
