The Belgian Athletics Championships (Dutch: Belgische kampioenschappen atletiek; French: Championnats de Belgique d'athlétisme) is an annual outdoor track and field competition organised by the Royal Belgian Athletics League, which serves as the national championship for the sport in Belgium.

The competition programme features a total of 34 individual Belgian Championship athletics events, 17 for men and 17 for women.

[1] Men competed in a 200 metres hurdles until 1964, by which point the event had fallen out of favour in international competitions.

The women's programme was gradually expanded from the 1960s onwards, with the 1500 m appearing in 1969, the 3000 m in 1973, triple jump in 1991, hammer throw and pole vault in 1995, and steeplechase in 2001.

The women's combined event was the athletics pentathlon up to 1980 and the 3000 metres was extended to match the men's 5000 m distance in 1995.
