Oskaloosa derives its name from Ouscaloosa who according to town lore was a Creek princess who married Seminole chief Osceola. It means "last of the beautiful." (This interpretation of "last of the beautiful" is not correct. "Oskaloosa" in the Mvskoke-Creek language means "black rain" from the Mvskoke words "oske" (rain) and "lvste" (black). "loosa" is an English corruption of the Mvskoke word "lvste". See for example the Wikipedia entry for "Tuskaloosa". In addition the Mvskoke word "Ouscaloosa" means "Black Water").  The first white settlers arrived in 1835 led by Nathan Boone, youngest son of Daniel Boone who acting on instructions from Stephen W. Kearny selected it to be the first site of Fort Des Moines on a high ridge between what Skunk River and Des Moines River. The ridge was originally called the Narrows.
On January 6, 1882, most of the buildings in the north half of Oskaloosa were severely damaged and most of the plate glass windows in the area were broken by an explosion. Three boys were killed in the explosion. The boys had been seen shooting at the A. L. Spencer gunpowder magazine half a mile north of the town center.
In the 1880s, over a million tons of bituminous coal was mined in the area from 38 mines. The first mine in the area was opened shortly after 1853 by Robert Seevers, who in 1853 drove a drift into a 4-foot coalbed in an exposed creek bank east of town. Initially, coal was mined entirely for local consumption, but with the arrival of the railroads, coal from the region was shipped widely. By 1887, the report of the state mine inspector listed 11 coal mines in and around Oskaloosa. The coal output of Mahaska County surpassed that of all other Iowa counties by 1895, by which time, the output had reached over a million tons per year. In 1911, coal mining was reported to be the primary industry in the region. In 1914, the Carbon Block Coal Company of Centerville produced over 100,000 tons of coal, ranking among the top 24 coal producers in the state.
There were several major coal-mining camps in the Oskaloosa area. Muchakinock was about 5 miles south of town, on the banks of the Muchakinock Creek. Lost Creek was a mining camp about 8 miles southeast of town. On January 24, 1902, there was a mine explosion in the Lost Creek No. 2 mine. This was one of only two major mine disasters in Iowa between 1888 and 1913. A miner setting shots to blast coal from the coal face re-used a hole left over from a previous failed shot, and the result was a coal dust explosion that detonated barrels of gunpowder stored in the mine. 20 men died on the site and 14 more were badly injured. The explosion sparked a state-wide miner's strike, and as a result, the following April, a law was passed regulating blasting in coal mines.

Oskaloosa is the home of William Penn University, a private, liberal arts college. It was founded by members of the Religious Society of Friends (Quakers) in 1873 as Penn College. In 1933, the name was changed to William Penn College, and finally to William Penn University in 2000.
Oskaloosa was the home of the now-defunct Oskaloosa College.
The city's public system, Oskaloosa Community School District, operates a high school, middle school, elementary school, and an alternative school. Oskaloosa Elementary opened in January 2005, merging five smaller buildings scattered across the city. The building is the largest elementary school in Iowa.
In the city's town square is a bronze statue of Chief Mahaska, the 19th-century leader of a Native American tribe called the Ioways, for whom Mahaska County was named. Recently restored, the artwork was completed in 1907 by an Iowa-born sculptor named Sherry Edmundson Fry (1879–1966). At the time it was commissioned, Fry was living in Paris. He returned to Iowa the following summer to make preparatory drawings of Meskwaki at the nearby Settlement at Tama, Iowa, and to collect Indian artifacts and other reference materials. Returning to Paris, he began on a clay scale model, which he first showed at the Paris Salon in 1907. A year later, he exhibited the final full-sized sculpture, for which he won the Prix de Rome. Soon after, it was shipped to the US, and arrived in Oskaloosa by railroad in September. The formal dedication of the statue, which was attended by a crowd of about 12,000 people, was held on May 12, 1909.
Oskaloosa boasts two private homes designed in 1948-51 by American architect Frank Lloyd Wright. Typical of his Usonian homes, these include the Carroll Alsop House at 1907 A Street, and the Jack Lamberson House at 511 North Park Avenue.
Oskaloosa hosted the Iowa State Fair prior to the Civil War in 1858 and 1859.
In 1934, Oskaloosa became the first city in the United States to fingerprint all of its citizens, including children.
The city is mentioned in country and western singer Johnny Cash's song "I've been everywhere".
Municipal Band & Historic Bandstand 
The first settlers in the area brought along their instruments and the universal, deep love of music. That led to the organization of a band in 1864. In 1880 the band was called the K. T. Band (for Knight Templars). It was about 1882 when a double-deck bandstand was erected in the center of the city park. The band started playing in the city park when it was just a field. The construction of a brick walk through the park was done with money obtained from a local talent minstrel show. In 1886 the K. T. Band went to St. Louis for their national conclave and was a tremendous hit. That marked the beginning of the band's prominence in the Midwest.
It was the genius of Charles L. Barnhouse that developed the band “atmosphere” from the time he came to Oskaloosa in 1891. He exerted a creative influence to build up a musical organization that would become the pride of the city. His band grew to statewide acclaim, becoming the official band of the Iowa State Fair for four years. In 1904 the band became even more well known when it played at the National K.P. encampment in Louisville, Kentucky, and stopped off en route, by invitation, to play at the World's Fair in St. Louis. In the ensuing years the band became popular throughout Iowa and other states.
In 1907 and 1908 Oskaloosa had two bands playing concerts – the Iowa Brigade Band and LaRue's Band. The merchants on High Avenue West employed their own band to compete with the Iowa Brigade Band in the park on Saturday evenings.
In 1911 the citizens decided to beautify the city and they voted to fund improvements for the city park. The citizens recommended that a new bandstand be erected in the center of the park. The old double deck frame bandstand was moved to one side to be used while the new bandstand was being built. The first concert in the new bandstand was played on June 1, 1912, and the bandstand was dedicated on July 25, 1912.
