The day saw a range of stalls, food and drink, crafts, on-stage entertainment, and fireworks, plus the switch-on of the lights and Christmas tree.
Dancers, singers, and cheerleaders took to the stage throughout the day and featured a performance from local band, The Sods.
Retford saw special appearances from Stormtroopers, Rattlejag Morris, giant stilt-walking elves, and a flying Santa around the town.
Santa arrived at noon at the Town Hall before switching on the lights at 5pm with the help of his lucky assistant - Willow - who was chosen at random from entries completed at the grotto.
Here is a selection of pictures from the event.
