Frogmore Cottage is a historic Grade II listed home on the Frogmore estate, which is part of Home Park in Windsor, England. Built in 1801 at the direction of Queen Charlotte in the gardens near Frogmore House, Frogmore Cottage is part of the Crown Estate, the monarch's public estate. The cottage became the residence of the Duke and Duchess of Sussex in the United Kingdom in 2019, and was their primary residence before they moved to Montecito, California in the United States. In March 2023, an agent of the couple said that they had been requested to vacate it.
