Storm names
The following list of names was used for named storms that formed in the Northeastern Pacific in 2005. The names not retired from this list were used again in the 2011 season. This was the same list used in the 1999 season. The names Todd and Veronica were used for the first time this year.

For storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the area between 140 degrees west and the International Date Line, all names are used in a series of four rotating lists. The next four names that were slated for use in 2005 are listed below.

Retirement
On April 6, 2006, at the 28th session of the RA IV hurricane committee, the World Meteorological Organization retired the name Adrian from its rotating name lists due to the amount of damage and deaths it caused, and it will not be used again for another Pacific hurricane. Adrian was replaced with Anthony for the 2011 season.
