The 2003 Atlantic hurricane season was a very active season with tropical cyclogenesis occurring before and after the official bounds of the season—the first such occurrence since the 1970 season. The season produced 21 tropical cyclones, of which 16 developed into named storms; seven of those attained hurricane status, of which three reached major hurricane status. The strongest hurricane of the season was Hurricane Isabel, which reached Category 5 status on the Saffir–Simpson hurricane scale northeast of the Lesser Antilles; Isabel later struck North Carolina as a Category 2 hurricane, causing $3.6 billion in damage (2003 USD) and a total of 51 deaths across the Mid-Atlantic region of the United States.

Although the bounds of the season are typically from June 1 to November 30, the season began early with the formation of Subtropical Storm Ana on April 20, and it ended relatively late on December 11 with the dissipation of Tropical Storm Peter. In early September, Hurricane Fabian struck Bermuda as a Category 3 hurricane, where it was the worst hurricane since 1926; on the island it caused four deaths and $300 million in damage (2003 USD). Hurricane Juan caused considerable destruction to Nova Scotia, particularly Halifax, as a Category 2 hurricane, the first hurricane of significant strength to hit the province since 1893. Additionally, Hurricanes Claudette and Erika struck Texas and Mexico, respectively, as minimal hurricanes. In December, Tropical Storm Odette struck the Dominican Republic, and Tropical Storm Peter formed in the eastern portion of the basin.
