Hurricane Edna was a deadly and destructive major hurricane that impacted the United States East Coast in September of the 1954 Atlantic hurricane season. It was one of two hurricanes to strike Massachusetts in that year, the other being Hurricane Carol. The fifth tropical cyclone and storm of the season, as well as the fourth hurricane and second major hurricane, Edna developed from a tropical wave on September 2. Moving towards the north-northwest, Edna skirted the northern Leeward Islands as a tropical depression before turning more towards the west. The depression attained tropical storm status to the east of Puerto Rico and strengthened further to reach hurricane status by September 7. The storm rapidly intensified and reached its peak intensity of 125 mph (205 km/h) north of the Bahamas before weakening to Category 2 status near landfall in Massachusetts on September 11. Edna transitioned into an extratropical cyclone in Atlantic Canada before its remnants dissipated in the northern Atlantic.

Edna caused 29 fatalities throughout its lifetime as a tropical cyclone, as well as a moderate amount of damage. It first caused rainfall-induced flooding in Puerto Rico, and it later brushed the Bahamas. High waves affected the coastline of North Carolina. Edna resulted in the heaviest day of rainfall in New York City in 45 years, while strong waves cut off Montauk from the remainder of Long Island. There were six highway deaths in the state, and $1.5 million in crop damage. There were widespread evacuations in southern New England, after Hurricane Carol struck the same area only 11 days prior. Strong winds caused extensive power outages for 260,000 people, including nearly all of Cape Cod. Edna became the costliest hurricane in the history of Maine, where the hurricane caused flooding that washed out roads and rail lines. There were 21 deaths in New England, eight of whom in Maine due to drownings. Later, high winds severely damaged crops in Atlantic Canada.
