Juliette Gordon Low (October 31, 1860 – January 17, 1927) was the founder of Girl Scouts of the USA, with help from Sir Robert Baden-Powell, the founder of the Scouting Movement. Low and Baden-Powell both shared a love of travel and support of the Girl Guides. Juliette Low joined the Girl Guide movement, forming a group of Girl Guides in the United States in 1897.

In 1912 she returned to the United States, and established the first U.S. Girl Guide troop in Savannah, Georgia, that year. In 1915, the United States' Girl Guides became known as the Girl Scouts, and Juliette Gordon Low was the first president. She stayed active until the time of her death in 1927.

Her birthday, October 31, is commemorated by the Girl Scouts as "Founder's Day".
