Henry Augustus Ward (March 9, 1834 – July 4, 1906) was an American naturalist and geologist.

[1] After attending Williams College and the Lawrence Scientific School, Harvard, where he was an assistant of Louis Agassiz, he traveled in Egypt, Arabia, and Palestine, and studied at the Jardin des Plantes, the Sorbonne, and the School of Mines in Paris, and at the universities of Munich and Freiberg.

In Rochester, he founded Ward's Natural Science, a pioneer enterprise of its kind, which collected specimens from all parts of the world, and then mounted and sold them to colleges and museums.

His ashes were interred in Mount Hope Cemetery in a niche in his granite monument.

His monument is surmounted by a glacial erratic boulder which shows jasper inclusions.
