Petronilla Deterville, MBE (14 May 1951-3 October 2010) was a St. Lucian musician and composer recognized for her work in founding youth music and theatrical groups.

Petronilla de Meath (c. 1300–1324) was the maidservant of Dame Alice Kyteler, a fourteenth century Hiberno-Norman noblewoman. After the death of Kyteler's fourth husband, Kyteler was accused of practicing witchcraft and Petronilla was charged with being one of her accomplices. Petronilla was tortured and forced to proclaim that she and Kyteler were guilty of witchcraft. Petronilla was then flogged and eventually burnt at the stake on 3 November 1324, in Kilkenny. Hers was the first known case in Ireland or Great Britain of death by fire for the crime of heresy.
