The Saddle-billed stork ('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 possesses a longer, more slender neck and slightly longer legs than the other storks, so the saddle-billed is likely to be the tallest extant species of the family. Its extremely long legs measure up to 36.5 cm (14.4 in) in tarsus length. The long bill measures from 27.3 to 36 cm (10.7 to 14.2 in). The sexes can be readily distinguished by the golden yellow irises of the female and the brown irises and dangling yellow wattles of the male. It is therefore one of the few storks to display sexual dimorphism in colour.

This is a huge bird that regularly attains a height of 145 to 150 cm (4 ft 9 in to 4 ft 11 in), a length of 142 cm (4 ft 8 in) and a 2.4 to 2.7 m (7 ft 10 in to 8 ft 10 in) wingspan. Reportedly adult saddle-billed storks in captivity can attain a height of up to 150 to 180 cm (4 ft 11 in to 5 ft 11 in). The male of the species is larger and heavier than the female, with a range of 5.1–7.52 kg (11.2–16.6 lb), with a mean mass of 6.38 kg (14.1 lb). The female is usually between 5 and 6.84 kg (11.0 and 15.1 lb), with a mean mass of 5.95 kg (13.1lb).
