Self-help or self-improvement is a self-guided improvement—economically, intellectually, or emotionally—often with a substantial psychological basis.

When engaged in self-help or self improvement, people often use publicly available information or support groups, on the Internet as well as in person, where people in similar situations join together. From early examples in self-driven legal practice and home-spun advice, the connotations of the word have spread and often apply particularly to education, business, psychology and psychotherapy, commonly distributed through the popular genre of self-help books. According to the APA Dictionary of Psychology, potential benefits of self-help groups that professionals may not be able to provide include friendship, emotional support, experiential knowledge, identity, meaningful roles, and a sense of belonging.

Many different self-help group programs exist, each with its own focus, techniques, associated beliefs, proponents and in some cases, leaders. Concepts and terms originating in self-help culture and Twelve-Step culture, such as recovery, dysfunctional families, and codependency have become firmly integrated in mainstream language. Groups associated with health conditions may consist of patients and caregivers. As well as featuring long-time members sharing experiences, these health groups can become support groups and clearing-houses for educational material. Those who help themselves by learning and identifying health problems can be said to exemplify self-help, while self-help groups can be seen more as peer-to-peer or mutual-support groups.
