MENTOR / The National Mentoring Partnership is an advocate and resource for mentoring in the United States. It is a 501(c)(3) nonprofit organization, with headquarters in Alexandria, Virginia.

Mentoring is a tool for helping children and youth succeed in life. Although nearly 17.6-million young Americans need or want a mentor,^{[citation needed]} only about three million are in formal, high-quality mentoring relationships. That means nearly 15-million young people are still in need today.

MENTOR’s mission is to expand the power of mentoring to the millions of young Americans who want or need adult role models.

MENTOR shares information, national standards, and best practices so that the mentoring community can work effectively and efficiently. It works with the organizations that directly match and oversee the mentor-mentee pairs, and helps individuals mentoring opportunity in their communities.

Throughout the month of January - National Mentoring Month - and year-round, the Harvard Mentoring Project, MENTOR/National Mentoring Partnership, and the Corporation for National and Community Service are spearheading the effort to raise awareness of ways that individuals can lend their support to this important cause. People interested in becoming mentors are asked to go to MENTOR official website, where they can find organizations offering mentoring opportunities in their local community. Harvard's WhoMentoredYou project features videos of Quincy Jones, Clint Eastwood, Oprah Winfrey, Colin Powell, and other well-known individuals talking about their mentors.
