Song Hye-Kyo was born on November 22, 1981, in Daegu, South Korea. At the time of her birth, she was seriously ill, leading doctors and her parents to fear that she might not survive. After her recovery, her birth was officially registered on February 26, 1982. This discrepancy in her birth date has led to some confusion over the years.

During her early childhood, Song’s parents divorced, and she was raised by her mother. The two eventually moved to the Gangnam District in Seoul. While attending elementary school, Song began practicing figure skating but discontinued the sport by the eighth grade. Although she describes herself as introverted and shy, her high school teacher characterized her as cheerful and sociable.
