List of Washington state symbols

These symbols, which reflect the history and culture of the state, are often opportunities for politicians to "tie themselves to popular symbols", for teachers to highlight the legislative process to their students, and for lobbyists to "have their products given official designation".

While most states have an official motto and nickname, Washington's motto ("Al-ki", meaning "by and by" in Chinook Jargon) and nickname ("The Evergreen State") have never been officially adopted by the Legislature.

The newest symbol of Washington is state dinosaur, "Suciasaurus rex", which was declared in 2023.

"Al-ki", meaning "by and by" in Chinook Jargon, is the state's unofficial motto, first appearing on the territorial seal designed by Lt. J.K. Duncan.

[24] The designation of sasquatch as the state's official cryptid or monster has been proposed since the 1970s, going as far as a joke proclamation issued by Governor Daniel J. Evans in 1970.
