Regional definitions vary from source to source. The states shown in dark red are usually included, while all or portions of the light red states may or may not be considered part of the West Coast.
The "'West Coast'", "'Western Seaboard'", or "'Pacific Seaboard'" are terms for the westernmost coastal states of the
Western United States, comprising most often
California,
Oregon and
Washington.
Arizona and
Nevada, while not coastal states, are also often included in the West Coast due to their proximity to the Pacific Coast and their economic and cultural ties to California (such as Arizona's two largest universities which are members of the
Pacific 10 Conference). Although not part of the
contiguous United States,
Alaska and
Hawaii do border the
Pacific Ocean and could be included in the West Coast. As of 2005, the estimated population of the West Coast ranged from approximately 45–55 million, depending on which states are included in the estimate.

An older term, thought to have arisen in the
Northeastern United States, refers to the West Coast simply as "the Coast." The West Coast can also be referred to jokingly as the "
Left Coast", a pun based on its lefthand position on a north-centric
map of the U.S., as well as its reputation for being more politically liberal (or "left-wing") than other parts of the United States. California is often perceived as the core of the region.
