The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school. The process of jumping directly from high school basketball to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who enter the draft be 19 years of age or older and at least one year removed from high school.

Reginald Hezeriah Harding was an American professional basketball player. He starred while playing at Eastern High School in his hometown of Detroit, Michigan, and entered the 1962 NBA draft without playing college basketball due to eligibility issues. Harding was selected by the Detroit Pistons as the first player drafted into the National Basketball Association (NBA) without having played in college.
