List of Idaho state symbols

The state's second symbol was its motto, which was chosen shortly after Idaho was admitted to the Union in 1890.

Three symbols have been adopted that were proposed by students; the Appaloosa became the state horse in 1992 following a proposal from sixth-graders from Eagle, Idaho, and in 1992 elementary school students in Boise introduced the monarch butterfly as the state insect.

In 2023 Idaho's most recent symbol, Oryctodromeus cubicularis, was adopted as the state dinosaur following a proposal from students at Ucon Elementary.

For example, the mountain bluebird, Idaho's state bird, is also an official symbol for Nevada.

[28] In the 2010s, a student proposal for the rattlesnake as the state reptile was unsuccessful since farmer-legislators considered the snake a "pest".
