Tilgate Park, Goffs Park and the Memorial Gardens in the town centre, have all retained their Green Flag status.
The Green Flag Award Scheme is handed out by environmental charity Keep Britain Tidy to recognise and reward the best green spaces in the country.
This is the twelfth year since 2002 that Tilgate Park has received the award.
Goffs Park has now been awarded the Green Flag six times.
The Memorial Gardens has also received its sixth Green Flag.
Cllr Duncan Crow, Cabinet member for Leisure and Culture, said: “The fact that we keep earning the award shows the dedication and hard work of the council, its staff and community groups in maintaining and continuously improving the town’s green spaces.”
