Chaim Walder (born 1969) is an Israeli Haredi rabbi and author of literature for children, adolescents, and adults. In 1993, he became an Israeli publishing sensation with his first book, Yeladim Mesaprim al Atzmam (Hebrew: ילדים מספרים על עצמם‎, Children Talk About Themselves, translated into English as Kids Speak), which revolutionized literature for Haredi children by introducing young protagonists who speak openly about their problems and feelings.
