The Missouri State Museum is where visitors go to immerse themselves in the history of the Show-Me State. The museum houses an impressive collection of exhibits portraying the state's natural and cultural history. Museum staff provide tours of the Capitol and also manage Jefferson Landing State Historic Site, including the Elizabeth Rozier Gallery.

The Missouri State Museum is located on the first floor of the Missouri State Capitol Building and is managed by the Missouri Department of Natural Resources. The museum continues to showcase Missouri's diverse history and resources. The museum houses both temporary and long-term exhibits, such as exhibits for the 150th anniversary of the Civil War. One of the highlights of the museum's collections is a significant and rare group of over 125 Civil War battle flags. Many of the flags belonged to, or were captured by, Missouri units on both sides of the war. At least one flag is on display at all times in the museum. Missouri was one of the most divided states during the Civil War and the Missouri State Museum exhibits tell this story. The museum is open seven days a week, from 8 am - 5 pm Monday - Friday and 9 am - 4 pm Saturday and Sunday. Free admission. Closed New Years Day, Easter, Thanksgiving, and Christmas.
