Paul Alton "Lil' Buck" Sinegal (January 14, 1944 – June 10, 2019) was an American blues and zydeco guitarist and singer. Paul Alton Senegal was born in Lafayette, Louisiana.

According to researchers Bob Eagle and Eric LeBlanc, the spelling "Sinegal" rather than "Senegal" was the result of a passport error, which he never corrected. Senegal was nicknamed "Little Buck" (for buckwheat) or "Lil' Buck" because of his short stature. Senegal’s mother, Odette Broussard, played guitar.
