Henry Perkins Bryant (May 12, 1820 – February 2, 1867) was an American physician and naturalist. He collected specimens, particularly birds and mammals, from the Caribbean and North America. A number of subspecies were described from his collections and several were named after him including Bryant's Savannah Sparrow Passerculus sandwichensis alaudinus, Bryant's Golden Warbler Dendroica petechia bryanti, Agelaius phoeniceus bryanti and Bryant's Grassquit Tiaris olivaceus bryanti.
