Marshall's iora (Aegithina nigrolutea), also known as the white-tailed iora, is a songbird in the genus Aegithina found in parts of India and Sri Lanka.
The diagnostic features of the species are the short wing and tail; white edging to tertials converging broadly at the tip, versus tertial tips black to only narrowly white in tiphia and a smaller and shorter bill than tiphia from any part of India. The vocalizations are also different. The species is best known from northwestern India, however only a few verified specimen records exist from southern India. It is now also known from Sri Lanka.
