Competitions in the sport of skateboarding, governed by World Skate, have been held at two editions of the Summer Olympic Games. First selected as one of the discretionary sports at the 2020 and 2024 games, skateboarding will be inducted as one of the mandatory sports at the 2028 games. Athletes compete in the disciplines of park and street skateboarding – each their own events. Japan has won both the most gold medals (5) and most medals overall (9). [Wikipedia]
