Adaline Shepherd (August 19, 1883 to March 12, 1950) was an American composer of piano pieces. Though she did not compose many pieces, the pieces she composed were popular. In her twenties, she composed three ragtime pieces: Pickles and Peppers (1906), Wireless Rag (1909), and Live Wires Rag (1910). Commemorating World War I, she also published a Victory March (1918). She married Frederick Sherman Olson in 1910, and thereafter used his last name as her own.
After her marriage, she retired from composition, and her compositions were unknown to her remaining family by the 1970s until they were contacted by reporters.
