The November 2009 nor'easter was a powerful autumn nor'easter that caused widespread damage throughout the east coast of the United States. This extratropical cyclone formed in relation to Hurricane Ida's remnant mid-level circulation across southeastern Georgia and moved east-northeast offshore North Carolina, before slowly dropping south and southeast over the succeeding several days. The system eventually dissipated on November 17.

A nor'easter, is a large-scale extratropical cyclone in the western North Atlantic Ocean. The name derives from the direction of the winds that blow from the northeast. The term is commonly used in the winter in New England and Atlantic Canada.
