The March 2010 nor'easter or St. Patrick's Day nor'easter was a powerful nor'easter that impacted the Northeastern United States and Eastern Canada from March 12–16, 2010, resulting in at least nine deaths. The slow-moving storm produced over 10 inches (25 cm) of rain in New England, causing widespread flooding of urban and low-lying areas. Winds of up to 70 miles per hour (110 km/h) snapped trees and power lines, resulting in over one million homes and businesses left without electricity. The storm also caused extensive coastal flooding and beach erosion. The nor'easter was the fifth major winter storm to impact the Mid-Atlantic and New England in the 2009–10 North American winter storm season.
