If the plans go ahead, vehicles will be replaced with planters and ornamental bollards.
The council's cabinet member for neighbourhoods councillor Julie Leigh said: "Kings' Park is a fantastic place for visitors and Retfordians alike, but we have to ensure it remains accessible and safe.
"By removing the clutter of vehicles around the entrance we will not only increase the visibility for people crossing Chancery Lane, but provide a more attractive and appealing gateway into the park."
The council is currently consulting on its plans. A spokesman said design work was likely to be done in-house.
