Most of Muddy was built recently: 4% of its homes predate 1940 and the median home dates from 1952. Below: maps from 1908 on and the census since 1960.
During the 19th century, the site of Muddy was home to a small settlement known as Robinson's Ford, which was among the communities considered for the seat of Saline County after the county's creation in the 1840s. The modern village of Muddy had its start as a mining settlement established by the Harrisburg Big Muddy Coal Company, for which it was named, in 1903. The mine was sold to the larger O'Gara Coal Company in 1906.
The former St. Ioasaph Orthodox Church in Muddy, built in 1913, is dedicated to Ioasaph of Belgorod. The church was located on South St. at 37°45′56″N 88°31′21″W. This church was attended by eastern European immigrants, including Russians, Slovaks, Poles, and Rusyns. It was dismantled in 2019.
