The Asian Marathon Championships is a biennial international competition in marathon road running for Asian athletes. Organised by the Asian Athletics Association, its creation in 1988 followed decision to drop the 42.195-kilometre (26-mile and 385-yard) race from the programme of events at the Asian Athletics Championships. In that competition, championship marathons were held for men in 1973 and 1975, then finally for both men and women at the 1985.
