Humayun Abdulali (19 May 1914, Kobe, Japan - 3 June 2001, Mumbai, India) was an Indian ornithologist and biologist who was also a cousin of the "birdman of India", Salim Ali. Like other naturalists of his period, he took an initial interest in shikar (hunting). Unlike Sálim Ali, his main contributions were less field-oriented and based more on bird collections, particularly those at the Bombay Natural History Society where he worked for most of his life.
