The Ohio Healthy Homes Network (OHHN) is a 501(c)(3) non-profit statewide organization whose mission is to promote healthy, safe, and affordable housing for people of all ages. OHHN was formed in 1997 as Help End Lead Poisoning and continues to focus on ensuring that Ohio families have access to lead-safe housing. In 2011, OHHN expanded its mission to focus more broadly to address health-related housing issues like indoor environmental quality and establishing and preserving affordable, healthy housing.

OHHN is a member of the Leadership Team for the Ohio Lead Free Kids Coalition, a collection of organizations and individuals who share a deep and urgent concern about the potentially life-long harm caused by lead poisoning.
