The UCI Mountain Bike Marathon World Championships (en. UCI Mountain Bike Marathon World Championships) are one of the cycling world championships. These are in-line races (or long circuits) with a mileage of more than 60km (approximately 5 hours of racing). Resistance matters a lot.

In the first edition, 2003, the marathon was included in the program of the mountain bike world championships, while since the 2004 edition separate championships have been held.
