Douglas Wayne Sahm (November 6, 1941 – November 18, 1999), was a musician from Texas. Born in San Antonio, Texas, he was a child prodigy in country music, but became a significant figure in blues, rock and other genres. Today Sahm is considered one of the most important figures in what is identified as Tejano music. He was the founder and leader of the 1960s rock and roll band the Sir Douglas Quintet, and later with Augie Meyers, Freddy Fender and Flaco Jimenez in The Texas Tornados, and also in Los Super Seven supergroup.
Sahm was proficient on dozens of musical instruments and was a lifelong baseball fan.
