UCI Cyclo-cross Dünya Şampiyonaları, Union Cycliste Internationale (UCI) tarafından organize edilen dünya siklo-çapraz şampiyonalarıdır. 2020'den başlayarak, her yıl altı etkinlik düzenlenmektedir - erkek elit, kadın elit, 23 yaş altı erkekler, 23 yaş altı kadınlar, 18 yaş altı erkekler (Erkekler Gençler) ve 18 yaş altı kadınlar (Genç Bayanlar). Geleneksel olarak, elit etkinlikler Pazar günü, diğer etkinlikler bir önceki gün Cumartesi günü yapılır.
UCI, kazanana bir altın madalya ve bir gökkuşağı forması verir. İkinci ve üçüncü sırada yer alan yarışmacılara gümüş ve bronz madalya verilir. Dünya şampiyonları bir sonraki yılki şampiyonaya kadar gökkuşağı formalarını giyerler, ancak sadece kazandıkları etkinlik türünde giyebilirler.
