The 1947 Pacific typhoon season has no official bounds; it ran year-round in 1947, 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 Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1947 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
Storms
Tropical Storm Anna
| Tropical storm (SSHWS) | |
 | |
| Duration | March 18 – March 20 |
|---|---|
| Peak intensity | 65 km/h (40 mph) (1-min); 1001 hPa (mbar) |
Anna originated from a vigorous tropical wave that moved west along the ITCZ during the days of March 16 and 17. On March 18 an approaching cold front caused the wave to congeal into a tropical low pressure system while about 415 miles (670 km) to the east of Davao. The system rapidly organized into a tropical storm and continued west. Anna made landfall on Mindanao on March 20 as a tropical depression and weakened quickly thereafter.
Little data is available for this system, however, the U.S. Air Weather Service noted that the storm was of little significance.

Carol formed east of the Philippines on June 17. It moved northwest and skimmed right past the most northern island as a 115 mph typhoon. After that, it began to weaken. Carol passed by Taiwan, and was about to hit mainland China, but it suddenly took a northeast track. Shortly thereafter, Carol dissipated on June 23.

 | |
| Duration | October 6 – October 14 |
|---|---|
| Peak intensity | 240 km/h (150 mph) (1-min); 918 hPa (mbar) |
The origins of Rosalind can be track on a tropical storm that intensified into a category 2 on October 6 and named Rosalind. Therefore, Rosalind continued to rapidly intensify from 964 to 918 mbar, reaching its peak intensity. After Rosalind reaches its peak intensity, slight wind shear causes Rosalind to weaken on a category 2 on October 10. It intensified into a category 3 before it moved slowly. It weakened to a category 1 and tropical storm. Rosalind dissipated on October 14.
Rosalind was the first super typhoon ever recorded in the Pacific Ocean.

Tropical Storm Irene formed on November 30 between the Philippine Islands. It strengthened to a tropical storm with 50 mph winds before it made landfall on one of the islands. It curved northeast and weakened to a tropical depression. But after exiting land, it restrengthened to a moderate tropical storm. But shortly thereafter, it became extratropical on December 3. The Japan Meteorological Agency analyzed it as a tropical depression, though it was actually a moderate tropical storm.
