Celebrated on 01/04/2026
Missouri is known as the 'Show Me State,' a nickname that originated from a speech by Congressman Willard Duncan Vandiver in 1899, who declared, 'I'm from Missouri, and you have got to show me.' The state is also the birthplace of the iconic Gateway Arch in St. Louis, which stands at 630 feet tall and is the tallest man-made monument in the United States.
National Missouri Day is observed annually on the third Wednesday in February, as part of a series of state-specific holidays recognized in the United States. While the exact origins of this particular observance are not well-documented, it is believed to have been established to honor Missouri's rich history and cultural contributions. The day was likely created by state proclamation or through grassroots efforts to celebrate Missouri's heritage, similar to other state holidays like National Texas Day or National California Day.
Over time, National Missouri Day has evolved from a niche observance into a widely recognized celebration. Today, it is marked by various events across the state, including historical reenactments, educational programs in schools, and community gatherings. Many Missourians use the day to explore local museums, such as the Missouri History Museum in St. Louis or the Harry S. Truman Presidential Library in Independence. Social media campaigns also play a role, with residents sharing photos and stories about their favorite Missouri landmarks and traditions.
