Santiago Jiménez, Jr. (aka Santiago Henriquez Jiménez) (born April 8, 1944) is a folk musician who has won a National Heritage Fellowship in 2000 for lifetime achievement in traditional Tex-Mex/folk music. His father, Santiago Jiménez Sr. was a pioneer of conjunto music. His older brother Leonardo "Flaco" Jiménez is considered by many the greatest Tejano accordionist ever, certainly the most famous. Santiago's style is more traditional than that of his brother Flaco, who is noted for mixing his music with many styles outside the Tejano mainstream.
Santiago performed at the 2006 National Folk Festival in Richmond, Virginia. In 2011 he performed at the 50th Anniversary Concert for Arhoolie Records, held in Berkeley, California. Portions of that performance appeared in the July-4th-Weekend, 2011 edition of the public radio program American Routes. President Obama awarded Santiago a 2015 National Medal of Arts on September 22, 2016 for his contribution to American music.
