Auguste François Marie Glaziou was a French landscape designer and botanist born in Lannion, Brittany.
As a student in Paris, he earned a degree in civil engineering and took classes at the Muséum national d'histoire naturelle. In 1858 at the request of Emperor Dom Pedro II, he relocated to Rio de Janeiro as director of parks and gardens.
In Brazil, Glaziou was responsible for landscape design at several sites, including the gardens at Quinta da Boa Vista, the residence of Brazilian royalty for much of the 19th century. During his tenure in Brazil he also participated in widespread plant collecting. While in Brazil, he also engaged in the exploring the relatively unexplored territory, today known Brasilia, Brazil's capital.
In 1897 he returned to France and settled in Bordeaux, where he worked on his personal herbarium.
The genus Neoglaziovia and numerous botanical species are named after him. With Antoine Laurent Apollinaire Fée, he was co-author of the two-volume Cryptogames vasculaire du Brésil.
