National Day of the Cowboy is observed in the United States every year on the fourth Saturday of July. This holiday celebrates cowboy culture and history, which has roots tracing back to medieval Spain and the hacienda system introduced by Spanish settlers in the Americas. The distinct cowboy culture of the American West evolved in the mid-19th century and was popularized by Wild West shows and Western movies. Events are hosted by ranches, cowboy heritage centers, and museums, featuring parades, rodeos, contests, demonstrations, and concerts. The holiday originated in Wyoming in 2005, following a bill sponsored by the National Day of the Cowboy organization aimed at preserving cowboy heritage. As of 2019, 15 states have established this holiday into law, including Texas, California, and Virginia. Celebrations can also include watching Western films or hosting cowboy-themed parties.
