Catherine Gotthoffer (born 1923) was the first life member of the American Harp Society (AHS), and is a prominent freelance harpist who served as president of the AHS twice.

Catherine Gotthoffer played the violin from a young age. It wasn't until she was about ten years old that she set her eyes on the harp. She then went on to study the harp at Julliard with Marcel Grandjany. While at school, she met her husband, a trumpet player, and in 1944, she married Robert Gotthoffer. After graduation, Robert served in the Navy and left Catherine plenty of time to pursue her career as a freelance harpist in New York. After her husband's discharge, they went to Dallas to audition for the new symphony there. They were accepted and lived there for seven years, with the exception of summers spent in New York City. Catherine then got a five year contract with MGM in Hollywood and during this time, had her two children, Ann and Richard. In 1970, she started teaching at the California Institute of the Arts. In addition to her busy schedule as a freelance harpist and teacher, Catherine was also very involved in the American Harp Society. She helped to found the Los Angeles chapter and later went on to serve as the president twice, from 1968 to 1970 and from 1972 to 1976. Catherine then became the first life member of the AHS.
