Gregory Macalister Mathews (September 10, 1876 - March 27, 1949) was an Australian ornithologist.

Mathews made his fortune in mining shares, and moved to England with his English bride around 1900. He wrote The Birds of Australia (twelve volumes, 1910-1927), assisted by Tom Iredale. He donated his ornithological library to the Australian Museum in 1940.
