The Blizzard of 2003, also known as the Presidents' Day Storm II or simply PDII, was a historic and record-breaking blizzard on the East Coast of the United States and Canada, which lasted from February 14 to February 19, 2003. It spread heavy snow across the major cities of the Northeastern and Mid-Atlantic states, making it the defining snowstorm of the very snowy winter of 2002–2003.

All cities from Washington, D.C. to Boston were covered in 15–30 inches (38–76 cm) of snow and those cities were brought to a standstill due to problems caused by temperatures and the snow. In Baltimore and Boston, this was the biggest snowstorm on record, with 28.2 and 27.5 inches (71.6 and 69.9 cm) respectively.
