Adelaide Avery Claflin (July 28, 1846 – May 31, 1931) was an American woman suffragist and ordained minister.

She lectured often on suffrage with Lucy Stone, Mary Livermore, and Julia Ward Howe.

Claflin was the author of occasional editorials and articles in Boston dailies, and a contributor to Woman's Journal.

He was a prominent member of the Methodist Church, and, on account of his eloquence, was often in earlier life advised to become a minister.

Her mother, of a practical, common-sense temperament, had much appreciation of nature and of scientific fact, and a gift for witty and concise expression of thought.

In 1884, she was elected a member of the Quincy school committee, and served three years in that position, being the first woman who held office in that town.
