Olga Marguerite Fricker (July 19, 1902 – November 20, 1997) was a Canadian-born dancer, educator and choreographer, a proponent of the Cecchetti method of ballet training.

She established the Concert Group, which danced to works by Bach, Strauss, and Liszt with the Detroit Symphony Orchestra.

[10] Fricker and Darby moved from Detroit to Los Angeles in 1953,[8] and opened a school there; it was successful enough to expand to three locations by 1960.

[15] Fricker's sister Josephine was the third wife of English-American writer Hugh Lofting, author of the Doctor Dolittle series of children's books.

[16] She also wrote the script for a play based on the series, Hugh Lofting's Doctor Dolittle (Dramatic Publishing, 1976).
