Rudolph the Red-Nosed Reindeer is an iconic Christmas song written by the American songwriter Johnny Marks in 1949. The song tells the story of a young reindeer named Rudolph who has a bright red nose that shines like a beacon in the dark, snowy weather. Despite his unique appearance, Rudolph is ostracized by the other reindeer because of his nose. However, when Santa's sleigh becomes lost in a foggy Christmas Eve, Rudolph's nose becomes a lifesaving tool, and he is finally embraced by the other reindeer.
