Madeleine Slade (Mirabehn) (November 22, 1892 – July 20, 1982), daughter of the British Rear-Admiral Sir Edmond Slade, was a British woman who left her home in England to live and work with Mohandas Gandhi, the leader of the Indian independence movement. She devoted her life to human development, the advancement of Gandhi's principles and the freedom struggle in India. In doing so, Gandhi gave her the name, Mirabehn, after Meera Bai, the great devotee of Lord Krishna.
Mirabehn during her stay in India once went to Gurukul Kangri to learn Hindi. Thereafter she went to Bhagwat Bhakti Ashram of Rewari established by Swami Parmanand Maharaj in order to be blessed by him. She also wrote to Mahatma Gandhi about her experiences there in Bhagwat Bhakti Ashram.
She was awarded India's second highest civilian honour, the Padma Vibhushan in 1982.
Actress Geraldine James portrayed her in Richard Attenborough's film, Gandhi, which premiered several months after Madeleine Slade's death in 1982.
