Robert L. May was an American retailer. He was best known for creating the fictional character Rudolph the Red-Nosed Reindeer.

Rudolph the Red-Nosed Reindeer is a fictional reindeer created by Robert L. May. Rudolph is usually depicted as the ninth and youngest of Santa Claus's reindeer, using his luminous red nose to lead the reindeer team and guide Santa's sleigh on Christmas Eve. Though he initially receives ridicule for his nose as a fawn, the brightness of his nose is so powerful that it illuminates the team's path through harsh winter weather. Ronald D. Lankford, Jr., described Rudolph's story as "the fantasy story made to order for American children: each child has the need to express and receive approval for his or her individuality and/or special qualities. Rudolph's story embodies the American Dream for the child, written large because of the cultural significance of Christmas."
