The 1971 Pacific typhoon season was an extremely active season that featured the second highest typhoon count on record. It has no official bounds; it ran year-round in 1971, 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 1971 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 Weather Bureau, which would later be reformed into the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) the following year. This can often result in the same storm having two names.
