Dame Elizabeth Posthuma Simcoe (22 September 1762 – 17 January 1850) was an English artist and diarist in colonial Canada.
Nine survived to adulthood; Katherine, their only child to be born in Upper Canada, and John Cornwall Simcoe died in infancy.
Elizabeth was a wealthy heiress, who acquired a 5,000-acre (2025 ha) estate near Honiton, Devon, and built Wolford Lodge, which remained the Simcoe family seat until 1923.
The townships of North, East and West Gwillimbury, just south of Lake Simcoe, Ontario, are also named after her family.
