Carmichaels Borough was settled in 1767 and incorporated in 1855 from Cumberland Township. Carmichaels was laid out by James Carmichael, who was a scout and woodsman. He obtained the title of the land in a trade with Thomas Hughes who went to Jefferson. Carmichael's covered bridge which crosses Muddy Creek was built in 1889 and continues to be used today. The first post office in Carmichaels began operating in 1822. Prior to that time, the building was a private residence that was constructed between 1795-1804.
The borough is also home to the Greene Academy, the academy is a unique historic structure of native fieldstone and brick. The original fieldstone section was built in 1791 as an Episcopal Church on land owned by James Carmichael. In 1810, the church trustees offered the use of their building for a school and the brick addition was added. As a pioneer in co-education, the Greene Academy had a Female Department as early as 1837. It continued to serve as the educational center of the county until the founding of Waynesburg College in 1849. With the building of the Carmichaels Borough School in 1893, the Greene Academy closed.
