Susan Elizabeth Frazier (May 29, 1864 – February 3, 1924) was a thought leader on the issues of women's and African Americans' rights and capacity.

She was an active and accomplished substitute teacher in New York City Public Schools at a time when such opportunities for African American women were very limited.

[1] On February 16, 1892 Frazier delivered an address to an audience of the Brooklyn Literary Union, called "Some Afro American Women of Mark" which has been referenced from its time of first presentation, through to contemporary books and dissertations today.

[1] During World War I she founded and was president of the Women's Auxiliary of the Old Fifteenth National Guard, an African American troop, and continued to work with the 369th Infantry as it became known.

[1][7] Frazier was among 15 New York City public school teachers who won a contest promoted in the spring of 1919 by the Evening Telegram.

They left for Europe on November 10, 1919 on the SS Royal George, receiving a leave of absence from their teaching positions.

[1] Upon her death in 1924, full military honors were held in the 369th Regiment Armory and her casket was draped with the American flag.
