Cornelia Maria Clapp (March 17, 1849 – December 31, 1934) was an American educator and zoologist, specializing in marine biology. She earned the first Ph.D. in biology awarded to a woman in the United States from Syracuse University in 1889, and she would earn a second doctoral degree from the University of Chicago in 1896. Clapp was the first female researcher employed at the Marine Biological Laboratory, as well as its first female trustee. She was rated one of the top 150 zoologists in the United States in 1903, and her name was starred in the first five editions of American Men of Science (now American Men and Women of Science).
