Adelaide Dorn Wallerstein McConnell (March 4, 1869 – June 12, 1942) was an American translator, medical doctor, lawyer, and clubwoman, based in New York City.

[11] "There is no better-known clubwoman in New York than Mrs. Harry Wallerstein," noted the cover of Broadway Weekly in 1904.

[12] She was president of the Woman's Legal Aid Society when it began in 1898,[13] and president of the Adelaide Wallerstein Auxiliary of the National Army Relief Association for Porto Rico; the latter organization sent books, blankets, and disinfectants to American soldiers during the Spanish–American War.

[16] She was also active in the Daughters of the American Revolution and the Women's Press Club of New York.

[1] She headed the Philocalian Society in 1907, a group of clubwomen who sought to discourage young women from drinking, low-cut gowns, and late-night socializing in New York.
