Santa Claus.

Santa Claus is a legendary figure who is the traditional patron of Christmas all over the world. His popular image is based on traditions associated with a 4th-century Christian Saint Nicholas.
According to tradition, he was born in the ancient Lycian seaport city of Patara, and, when young, he traveled to Palestine and Egypt. He became bishop of Myra. He distributed gifts to the needy.
His generosity and kindness gave rise to legends of miracles he performed for the poor and unhappy. He was reputed to have given marriage dowries of gold to three girls whom poverty would otherwise have forced into lives of prostitution, and he restored to life three children who had been chopped up by a butcher and put in a brine tub. In the Middle Ages, devotion to Nicholas extended to all parts of Europe.
The resulting image of Santa Claus in the United States crystallized in the 19th century, and he has ever since remained the patron of the gift-giving festival of Christmas.
Under various guises Saint Nicholas was transformed into a similar benevolent, gift-giving figure in The Netherlands, Belgium, and other northern European countries. In the United Kingdom Santa Claus is known as Father Christmas.
