Fountain County was officially created on December 30, 1825, the act taking effect      on April 1, 1826; the boundaries of the county have not changed since that time.It was named for Major James Fontaine of Kentucky who was killed at Harmar's Defeat (near modern Fort Wayne, Indiana) on October 22, 1790, during the Northwest Indian War.

The first Fountain County courthouse was a two-story frame building constructed in Covington in 1827; Abraham Griffith submitted the winning bid of $335. Two years later in 1829 it was decided that a brick building was needed, and plans were made for a new courthouse; but then an act of the legislature called for the county seat to be moved. In the end it was decided that the county seat should remain in Covington, and the brick courthouse was completed in 1833.

A third courthouse was commissioned in 1856, and was completed in 1857 at a cost of $33,500. The circuit court met for the first time in the new building in January 1860, and the building was largely destroyed by fire the same day. Isaac Hodgson was the architect for the rebuilt courthouse, which was first occupied in January 1861; the total cost, including the reconstruction, totaled $54,624.05. The current courthouse was built in 1936–37 at a cost of $246,734; it replaced the previous building which had been declared unsafe. It was constructed by the Jacobson Brothers of Chicago; the architects were Louis R. Johnson and Walter Scholar of Lafayette. The courthouse walls display many murals painted by Eugene Francis Savage and others from 1937 to 1940; the murals cover over 2,500 square feet of wall space and depict the settlement of western Indiana.
