Storm names[]
Within the Northwest Pacific Ocean, the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names. The Japan Meteorological Agency's RSMC Tokyo Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of 65 km/h, (40 mph). PAGASA assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has had an international name assigned to it. The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee. Should the list of names for the Philippine region be exhausted then names will be taken from an auxiliary list.
International names[]
During the season a total of 35 named tropical cyclones developed in the Western Pacific and were named by the Japan Meteorological Agency (JMA) when it was determined that they had become tropical storms. These names were contributed to a list of 140 names that were submitted by the fourteen members nations and territories of the ESCAP/WMO Typhoon Committee. All of these names were used for the first time this season.
| Nock-ten | Muifa | Merbok | Nanmadol | Talas | Noru | Kulap | Roke | Sonca | Nesat | Haitang | Nalgae | Banyan | Washi | Matsa | Sanvu | Mawar | Guchol |
| Talim | Nabi | Khanun | Vicente | Saola | Damrey | Longwang | Kirogi | Kai-tak | Tembin | Bolaven | Chanchu | Jelawat | Ewiniar | Bilis | Kaemi | Prapiroon |
Retirement[]
After the season, the Typhoon Committee announced that the names Merbok, Sanvu, Vicente, Ewiniar, and Bilis would be removed from the naming lists. In 2006, they were replaced by Petai, Choilong, Lan, Lepen and Maliksi, respectively. Also, the name Nabi was requested by South Korea to be removed in the list, and it was subsequently replaced by Doksuri. The name Kaemi was replaced by Gaemi, after it was found that Kaemi was a misspelling.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility, and any tropical cyclone that may move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. The names not retired from this list will be used again in the 2008 season.
Retirement[]
The names Unding, Violeta, Winnie, and Yoyong were retired by PAGASA and were replaced by Ulysses, Vicky, Warren, and Yesha for 2008.
