The 1955 Pacific typhoon season has no official bounds; it ran year-round in 1955, 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 season produced a large number of tropical storms but most of them were weak, and sources from American typhoon warning agencies often grossly overestimated the maximum wind speed of many systems which could not properly match with their respective central pressure observations.

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 1955 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Fleet Weather Center on Guam.
Systems
The rest of the storms, such as unnumbered and unnamed tropical depressions and storms, are only classified by the CMA while the JMA is sometimes rare before the 1960s - 1970s.
Typhoon Violet
Typhoon Violet formed on January 1 and dissipated on January 6. It peaked as a Category 1 typhoon by the JTWC before making landfall in Mindinao in the Philippines.
JMA Tropical Storm Two
Typhoon Wilda
Forming in an area full of islands, Wilda moved up into the open ocean where it reached typhoon strength. Shortly after, Wilda peaked in intensity as a lower-end category 2 cyclone. Wilda soon made a turn and began to weaken. Soon enough, Wilda had weakened under typhoon strength and dissipated on March 29.
Typhoon Anita
Anita formed as a tropical depression on April 17. Anita entered a phase of warm waters, and it rapidly intensified to a category 1 typhoon and even a category 2 typhoon later. Anita encountered on a phase of cool waters, and as a result, it gradually weakened. Anita but re-intensified into a category 1 typhoon on April 20. However, it weakened again on April 22 but again re-intensified to a category 1 and even a category 2 typhoon later. Anita reached its peak intensity as a category 3 typhoon. Anita encountered a strong wind shear and because of this, Anita rapidly weakened to a tropical storm. Anita weakened to a tropical depression on April 25. Later, Anita loses its identity and dissipated.
Typhoon Billie

JMA Tropical Storm Six
Typhoon Clara
Tropical Storm Dot
Typhoon Ellen
Tropical Storm 09W
Typhoon Fran
On July 18, a tropical depression formed southeast of Japan. It entered a phase of favorable environments and was soon upgraded into a tropical storm and named Fran. Fran then moved into a favorable environment and Fran was upgraded into a category 1 typhoon. Intensification occurred and Fran intensified from a category 1 to 4 typhoon and reached its peak intensity. After peaking in intensity, unfavorable environments made Fran to start a weakening trend. On July 20, Fran weakened to a category 2 typhoon and later weakened to a category 1 typhoon and even as a strong tropical storm. On July 21 of noon, Fran weakened to a tropical depression, and soon encountered with strong wind shear and dissipated. Fran became extratropical on July 21, before moving further to the east and dissipated on July 23.

Louise weakened to a category 2 typhoon and it started to affect the Kyūshū island of Japan and even weakened to a category 1 typhoon and affected Japan. Louise dissipated on September 30.
