OK-National (OK-N) is an international kart racing class sanctioned by the Commission Internationale de Karting (CIK-FIA) for drivers aged 14 and over. Debuting in international competition in 2023, OK-N is the secondary senior class in FIA championships to OK.
Approved by the FIA World Motor Sport Council in 2022, OK-N was designed as a simplified version of OK regulations to reduce costs for competitors. The class debuted in international competition the following year, being contested in several championships across Europe and the Middle East.
Its inaugural World Cup was held in 2024—with qualifying decided via national championships held in 12 countries—and won by Kyuho Lee. The Arrive & Drive World Cup hosted its first edition in 2025, using a modified OK-N engine in a single-design format.
