The saddle-billed stork or saddlebill (Ephippiorhynchus senegalensis) is a large wading bird in the stork family, Ciconiidae. It is a widespread species which is a resident breeder in sub-Saharan Africa from Sudan, Ethiopia and Kenya south to South Africa, and in The Gambia, Senegal, Côte d'Ivoire and Chad in west Africa. It is considered endangered in South Africa.

The saddle-billed stork is silent except for bill-clattering at the nest. Like most storks, it flies with the neck outstretched, not retracted like a heron; in flight, the large heavy bill is kept drooping somewhat below belly height, giving it a distinctive appearance. This makes it easily recognizable, even if seen from a distance. It has been suggested that due to the large size and unusual appearance in flight, this species is the basis for the "big bird" and kongamato cryptids.

The saddle-billed stork prefers protected areas that have a higher extent of open water compared to areas without other storks.
