Muriel Petioni (January 1, 1914 – December 6, 2011) was a medical doctor and community activist in Harlem. She was known as the "matron of Harlem health" because she sought to fulfill the healthcare needs of the underprivileged people in Harlem. She was born in Trinidad, but her father was exiled to Harlem in 1917 due to his opposition to the colonial government, and in 1919 the rest of his family joined him. Her father eventually became a medical doctor at the age of 40.
