Martha Flores was a Cuban radio host, journalist, singer, and actress. Born in Cárdenas, Matanzas, in 1928, her family moved to Havana when she was a child. She studied journalism at the Manuel Márquez Sterling School and later graduated as a stenographer and typist from the Professional School of Commerce in Havana. She left Cuba in January 1959 and began to work multiple jobs in Miami, which included producing a radio segment called La Voz de la Mujer on WMIE. According to Flores, hers was the first radio program in Miami to speak out against Castro's revolution.
A leading figure in Miami's Cuban diaspora radio market, she was known to her listeners as the "Queen of the Night." She worked at La Fabulosa WFAB in the late 1960s and then moved to Union Radio WOCN in 1976. In 1982, she developed the program La Noche y Usted at WRHC-Cadena Azul, eventually moving to WQBA in 1992 and WAQI Radio Mambí in 1996. The three hour program covered Cuban issues and local politics.
She was a spokesperson for various causes, including the elderly, cancer awareness, and animal protection programs. She was also involved in the work of Brigada 2506.
