Theodore Luqueer Mead (February 23, 1852 – May 4, 1936) was an American naturalist, entomologist and horticulturist.
As an entomologist he discovered more than 20 new species of North American butterflies and introduced the Florissant Fossil Beds in Colorado to the wider scientific world.
As a horticulturist, he is best known for his pioneering work on the growing and cross-breeding of orchids, and the creation of new forms of caladium, bromeliad, crinum, amaryllis and hemerocallis (daylily).
In addition he introduced many new semi-tropical plants, particularly palm varieties, into North America.
Recently a comprehensive historical biography of his life and times has been published.
