Margaret Richardson Dixon, usually known as Maggie Dixon (February 27, 1908 – June 21, 1970), was perhaps the most influential woman journalist of 20th century Louisiana. She was the managing editor of her state's capital city newspaper, the Baton Rouge Morning Advocate, from 1949 until her death some two decades later. She was also an active Democrat who championed prison reform, assistance to the mentally ill, and organized labor.
