Cornelia Maria Dow (November 10, 1842 – October 12, 1905) was an American philanthropist and temperance leader,[1][2] interested in charitable, philanthropic, and reformatory work in her home state of Maine.

[2][1] The range of her sympathies included the poor and unfortunate of every class, and her life was spent in personal and social ministries.

[1][2] When the Star in the East, the official organ of the Maine W.C.T.U., was in danger of suspension, Dow became its business manager and through her efforts, made it successful.

In her connection with the work of the W.C.T.U., Dow was the close friend and companion of Lillian M. N. Stevens, the national head of the W.C.T.U.

[3] When her mother, through the infirmities of age, was compelled to give up the responsibilities of housekeeping, Cornelia took her place at home and presided over the household until the death of her father in 1897.
