Elaina Marie Tuttle (November 9, 1963 – June 15, 2016) was an American behavioral geneticist and biology professor whose academic research focused on ornithology and study of the white-throated sparrow.

During her graduate and post-doctoral work, she investigated how bird sexual selection has evolved and the trade-offs in reproduction that have occurred alongside sperm competition mechanisms in sparrows and in the fairy wren.

The decades of work researching the sparrow at the Cranberry Lake Biological Station (CLBS) for Indiana State University resulted in her being given multiple awards and the President's Medal for her accomplishments.

[2] She attended Siena College for her undergraduate degree[1] and then the State University of New York at Albany for her Ph.D and, during her work for the former, began acting as a field assistant for professor Doug Fraser at the CLBS.

The latter part of her post-doctoral education took place at the University of Chicago with an additional fellowship in the lab of Stephen Pruett-Jones and another international trip instead to Australia to study the fairy wren.

[2] After completing her post-doctoral studies, Tuttle was hired as a faculty member and professor at St. Mary's College of Maryland where she ran her own undergraduate lab that focused around research conducted at the Cranberry Lake Biological Station.
