George Hebard Maxwell (June 3, 1860 – December 1, 1946) was an American attorney and lobbyist for water reclamation and communal irrigation projects. In 1899, he formed the National Reclamation Association and, in 1902, along with Democratic U.S. Representative Francis G. Newlands, helped pass the National Reclamation Act.
From the late 1890s to the 1940s, Maxwell was a known public advocate for social causes such as support of farming communities, city, and suburban gardening as a source of food supply as well as environmental issues. He is often considered to be "The Father of Reclamation."
