Rolla ('/r//ɒ//l//ə/) is a city in, and the county seat of, Phelps County, Missouri, United States. Its population in the 2020 United States Census was 19,943. It is approximately midway between St. Louis and Springfield along I 44. Its micropolitan statistical area consists of Phelps County, Missouri. It is the home of the Missouri University of Science and Technology, well known for its many engineering departments and computer science department. The headquarters of the Mark Twain National Forest is in Rolla. The city is also within the Ozark Highlands American Viticultural Area, with vineyards first established by Italian immigrants to the area.

The first European American settlers in Phelps County arrived in the early 19th century, working as farmers and iron workers along the local rivers, such as the Meramec, the Gasconade, and the Little Piney. In 1842, John Webber built the first house in what became the City of Rolla. Nine years later, railroad contractor Edmund Ward Bishop, considered to be the founder of Rolla, settled in the area. The state officially established Rolla as a town in 1858. Three stories account for how Rolla was named. One story, widely regarded as a folk legend, and acknowledged as such by the Phelps County Historical Society, arises from the competition between Rolla and neighboring Dillon, Missouri, to be designated the county seat. When Rolla was made the county seat in 1861, the residents of Dillon, having lost a round, were allowed to choose the name of the new city and named it Rolla, after a good for nothing hunting dog. Another story came from a citizens' meeting about naming the town. Webber was said to prefer the name Hardscrabble (which was used to describe the soils in the region) and Bishop pushed for the name Phelps Center. George Coppedge, representing new settlers from North Carolina, wanted to name the community after Raleigh. Bishop broke the three way tie by agreeing with Coppedge as long as the name was spelled properly for the region, Rolla. But the one story that has some first hand evidence to back it up was that it was named after Rolla Rose of St. Louis. He and others traveled to the area in the 1840s on a hunting trip. He carved his name on a tree so that they would not get lost. His widow, Adeline Rose, related this story in the St. Louis Globe newspaper on July 19, 1903. With numerous settlers from the South, many residents of Rolla leaned toward the Confederacy during the American Civil War; however, the town was taken by Union forces in June 1861. They built two minor forts — Fort Wyman and Fort Dette — during their occupation. Rolla was also the location of Camp Glover and Camp Davies. From 1863 to 1865, Rolla was the regimental headquarters of the 5th Missouri State Militia. For most of its history, Rolla has served as a transportation and trading center. In 1860, it became the western terminus of the first constructed leg of the St. Louis–San Francisco Railway, colloquially known as the "Frisco Line". Today, the BNSF Railway directly runs through the town. Rolla was also a regular stop along U. S. Route 66, as it is almost located exactly halfway between the larger cities of St. Louis and Springfield. Today, Interstate 44, U. S. Route 63, and Route 72 all run through Rolla.

Running through the city is the divide line that separates the vast Missouri watershed (via the Little Piney and the Gasconade) from the substantially smaller Meremec watershed (via the Bourbeuse).
