Thomas Gibson Lea was an American botanist who was born in Wilmington, Delaware. He was the older brother of the publisher, Isaac Lea and the younger brother of John Lea, who is known for his study of a cholera outbreak in Cincinnati, Ohio.
Lea was honored alongside Miles Joseph Berkeley in the naming of Berkleasmium in 1854, which is a genus of fungi belonging to the family Dematiaceae. Lea also lends his name to the lichen Phaeophyscia leana.
