At the 2024 Paris Olympics, the youngest competitor is 11-year-old Chinese skateboarder Zheng Haohao. She's just one year older than the youngest Olympian in history: 10-year-old Greek gymnast Dimitrios Loundras, who won a bronze at the 1896 Summer Olympics in Athens.
The oldest athlete at the Paris Games is Australian Mary Hanna, 69, who competes in equestrian. She's three years shy of the oldest-ever Olympic athlete, Oscar Swahn of Sweden, who clinched that record at the 1920 Antwerp Games.
