This is a list of notable autodidacts. The list includes people who have been partially or wholly self-taught. Some notables listed did receive formal educations, including some college, although not in the field(s) for which they became prominent.

Historical education levels

Because of the large increase in years of education since 1800, especially during the early 20th century, it is difficult to define autodidactism and to compare autodidacts during different time periods.
