The 1947 Pacific typhoon season had no official bounds, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the portion of the Pacific Ocean north of the equator and west of the International Date Line. Storms that form east of the dateline and north of the equator are called hurricanes, see the 1947 Pacific hurricane season are for more information. Tropical storms formed that across the entire Western Pacific basin were assigned a name by the Joint Typhoon Warning Center (JTWC). Tropical depressions in this basin monitored by the JTWC have a "W" suffix added to their number.

Overall, the 1947 Pacific typhoon season was extremely active in terms of total storms and typhoons. In fact, it had more total storms snd typhoons than any other typhoon season at the time. While its storm record would be eclipsed in the 1964 season, the 1947 season, as of 2012, still maintains the record number of typhoons recorded in one year (28), two more than what was observed in 1964, the next highest amount of typhoons observed in a single year.

An unusual feature about the season was the lack of any land impact. This was primarily due to El Niño–Southern Oscillation (ENSO) conditions persisting across the entire Western Pacific tropical cyclone basin, which steered storms away from land, causing no landfalls at all during the season. Another unusual feature about the season was that three storms performed abnormal movements. Dora, the strongest storm of the season, attained a minimum barometric pressure of 900 millibars (mb), making it the most intense tropical cyclone in the West Pacific basin until Typhoon Nina in 1953 surpassed it. Second, Typhoon Hannah became the first storm recorded to cross from the Western Pacific to the Central Pacific basin, an extremely rare event. Finally, Typhoon Chris existed six days into the new year, giving the 1947 Pacific typhoon season the latest end to any West Pacific tropical cyclone season on record.

Storm namesEdit

The following names were used to identify named storms that formed in the Western Pacific basin. These three naming lists were used for the 1947 and part of the 1948 seasons, with the JTWC identifying the storms. The first storm was named Anna and the last storm was named Chris. No names were retired due to the lack of impact in this season. Unused names are marked in gray.
