白腹海雕（拉丁文学名：Haliaeetus leucogaster）亦称白胸海雕，是鹰科的一种大型猛禽。

牠们居住在印度、亚洲南部及澳大利亚海岸。白腹海雕极为独特。成鸟有白色的头部、胸部及尾部。在飞行时，牠们黑色的翅膀跟白色的腹部形成强烈的对比。像所有海雕属的成员般，牠们的尾部很短，且呈楔子状。

跟牠们最接近的近亲为不知名的所罗门群岛海雕（Sanford's Sea-eagle）。牠们两个物种是一对复合种（species pair），就像所有海雕的复合种一般，这个复合种是由一个黑头的物种（所罗门海雕）和一个白头的物种（白腹海雕）组成的。牠们的爪子、喙和眼睛都像所有冈瓦那大陆海雕一样，颜色很深。这个复合种的成员的寻部或多或少都有一点儿较深的色素，但并非所有个体都会出现这情况。虽然牠们的不同之处大部分都是在于牠们的外观及生态学，但其实牠们的祖先在少于一百万年前才开始分裂（Wink et al., 1996）。

The white-bellied sea eagle (Haliaeetus leucogaster), also known as the white-breasted sea eagle, is a large diurnal bird of prey in the family Accipitridae. Originally described by Johann Friedrich Gmelin in 1788, it is closely related to Sanford's sea eagle of the Solomon Islands, and the two are considered a superspecies. A distinctive bird, the adult white-bellied sea eagle has a white head, breast, under-wing coverts and tail. The upper parts are grey and the black under-wing flight feathers contrast with the white coverts. The tail is short and wedge-shaped as in all Haliaeetus species. Like many raptors, the female is slightly larger than the male, and can measure up to 90 cm (35 in) long with a wingspan of up to 2.2 m (7.2 ft), and weigh 4.5 kg (9.9 lb). Immature birds have brown plumage, which is gradually replaced by white until the age of five or six years. The call is a loud goose-like honking.
