Hurricane John, also known as Typhoon John, was the farthest-traveling tropical cyclone ever observed worldwide. It was also the longest-lasting tropical cyclone on record globally at the time, until it was surpassed by Cyclone Freddy in 2023.^[1] John formed during the 1994 Pacific hurricane season, which had above-average activity due to the El Niño of 1994–1995,^[2] and peaked as a Category 5 hurricane on the Saffir–Simpson scale, the highest categorization for hurricanes.

Over the course of its existence, John followed a 13,180 km (8,190 mi) path from the eastern Pacific to the western Pacific and back to the central Pacific, lasting 31 days in total.^[3][4][5] Because it existed in both the eastern and western Pacific, John was one of a small number of tropical cyclones to be designated as both a hurricane and a typhoon. Despite lasting for a full month, John barely affected land at all, bringing only minimal effects to the Hawaiian Islands and the United States military base on Johnston Atoll. Its remnants later affected Alaska.
