Robert Koehler (November 28, 1850 – April 23, 1917) was a German-born painter and art teacher who spent most of his career in the United States.

In 1879, he was able to return to Munich with means furnished by George Ehret, of New York, whose attention had been drawn to the young artists's ambition and capabilities.

Koehler's work while in Munich won him silver and bronze awards from the Academy, and Bavaria's Cross of the Order of St. Michael.

Koehler then set himself up as head of a private art school; pupils included Alfons Mucha.

[2] Three notable paintings, "The Carpenter's Family," "At the Cafe," and his masterpiece "The Strike" were selected for display at the Columbian Exposition in Chicago in 1893.
