The 1959 Escuminac disaster (also to referred to as the Escuminac hurricane) was considered the worst fishing-related disaster in New Brunswick in 100 years. It occurred due to the extratropical remnants of an Atlantic hurricane. The storm was the third tropical cyclone and first hurricane of the 1959 Atlantic hurricane season, and developed from a tropical wave in the central Gulf of Mexico on June 18. It headed rapidly northeastward and struck Florida later that day. Shortly after entering the Atlantic Ocean, it strengthened into a tropical storm later on June 18. By the following day, it had strengthened into a hurricane. However, it transitioned into an extratropical cyclone about six hours later. The remnants struck Atlantic Canada, once in Nova Scotia and again in Newfoundland before dissipating on June 21.

In its early stages, the storm dropped moderately heavy rainfall in Florida, which caused damage to crops. A tornado near Miami and high tides on the west coast of the state also resulted in damage. Overall, losses in Florida were around $1.7 million (1959 USD). After becoming extratropical, the storm caused significant effects in Atlantic Canada. About 45 boats were in the Northumberland Strait between New Brunswick and Prince Edward Island, and they did not have radio to receive warning of the approaching storm. Rough seas of up to 49 ft (15 m) in height damaged or destroyed many boats. At least 22 fishing boats capsized with their crews, causing 35 fatalities. High winds also disrupted communications in some areas, and several houses were damaged, causing damage costing $750,000 (1959 CAD, $781,000 1959 USD). The event became the deadliest work-related disaster in New Brunswick.
