Adelaide Johnson (1859–1955) was an American sculptor whose work is displayed in the U.S. Capitol and a feminist who was devoted to the cause of equality of women.

This injury and award gave her the financial freedom to travel to Europe to study painting and sculpture, an opportunity she would never have had without the accident.

Johnson exhibited her work, The Portrait Monument and a bust of Caroline B. Winslow at The Woman's Building at the 1893 World's Columbian Exposition in Chicago, Illinois.

[4] The high point of her professional career was to complete a monument in Washington D.C. in honor of the women's suffrage movement.

Alva Belmont helped to secure funding for the piece, Portrait Monument to Lucretia Mott, Elizabeth Cady Stanton, and Susan B. Anthony, which was unveiled in 1921.

She relied on others for financial support and was often unwilling to sell her sculptures because she felt the prices offered did not recognize her work.
