Marshfield is a city in Webster County, Missouri, United States. As of the 2010 census, the city population was 6,633. It is the county seat  and part of the Springfield, Missouri Metropolitan Statistical Area.
Marshfield was settled in 1830. On May 28, 1856, the court instructed Wright Holland to lay out the county seat on a square in the southeast corner of the acres apportioned. The survey of the town was commenced June 21, 1856. The post office was established also in 1856, with Allan F. Goss as postmaster. (--State of Missouri, 1889, pp. 252–259.) 
Early growth was described as "very slow" until the opening of the railroad in 1870. Marshfield had 1 church, about 20 stores, 1 furniture factory and 2 wagon shops. (--Gazetteer of Missouri, Campbell, p. 643; Mr. T. Ballard Watters.)
On April 18, 1880, a tornado measuring F4 on the Fujita scale struck Marshfield. Its damage path was 800 yards (730 m) wide and 64 miles (103 km) long. The tornado killed 99 people and injured 100. It is said that 10% of Marshfield's residents were killed and all but 15 of its buildings were destroyed.
In 1948, President Harry S Truman visited the city. On July 4, 1991, President George H W and Barbara Bush visited the annual Fourth of July parade. The town boasts the oldest Fourth of July celebration in the state of Missouri, in fact, it's the oldest west of the Mississippi River, which is the reason the First Family chose Marshfield as a campaign stop on the nation's birthday.
