Hranoush Sidky Bey (circa 1881 – January 30, 1942), better known as Madame Bey, also Hranuş Sıdki Hanım, was an American boxing trainer. She ran a boxing camp for world champion boxers in Chatham Township, New Jersey, in the United States. Her life and boxing camp are documented in the book Madame Bey's: Home to Boxing Legends. Her prominence during the time she operated her boxing camp from 1923 to 1942 is documented in the thousands of press photos taken at her camp. Forgotten today, her camp's namesake was an everyday occurrence in sports sections of newspapers.
