Dr. Lindsey Doe is an American clinical sexologist and sex educator, best known for her online video series, Sexplanations.

In 2010, Doe was featured in the "Strong Woman Project", an art project at the Maureen and Mike Mansfield Library at the University of Montana. The project sought to portray diversity in the presentation of successful women.

Doe obtained her Bachelor's in Psychology in 2002 and her Master's in Health and Human Performance (with a specialty in health promotion) in 2005, both from the University of Montana. Doe then studied sexology at the Institute for Advanced Study of Human Sexuality, obtaining her doctorate in human sexuality in 2007.

From 2006 to 2014, Doe had taught a human sexuality course at University of Montana. In 2013, video blogging producer Hank Green partnered with Doe to create "Sexplanations", a video series explaining sexual topics. Doe and her channel have been called "a treasured presence" by Laci Green, the producer of sex ed show Sex+, who started on YouTube in 2008.

In March 2015 Doe received media attention for a YouTube video she uploaded to her personal "DoeEyes" account addressing an over-eager boy pursuing her daughter.
