Arthur Owen Marshall (November 20, 1881 – August 18, 1968) was an American composer and performer of ragtime music from Missouri.

Marshall had already taken some private lessons in classical music years before, and was versed with piano technique and a gift for syncopation.

Marshall also helped cover his school expenses by playing ragtime in public venues and for dances and special occasions.

He also played where work was available; in the brothels, where substantial tips regularly exceeded his standard wage by a great deal.

In 1903, despite flagrant racial discrimination, Marshall worked at the Louisiana Purchase Exposition (St. Louis World's Fair), playing piano at the Spanish Cafe where he earned $12 per week plus tips until he was replaced by a band.

However, he struggled to come to terms with Stark in 1906, possibly for his rag "The Pippin", and finally settled on a non-royalty offer of $10 and 200 copies of the music.
