A leather daddy is a term used in the leather subculture to describe a man who tends to dominate and has a fetish for leather. The leather subculture is a community of individuals who organize themselves around sexual activities that involve leather garments, such as leather jackets, vests, boots, chaps, harnesses, or other items. The term "daddy" can also refer to a senior or dominant partner in a leather or SM relationship, or to a social, political, or cultural identity within the community.

According to longtime scene chronicler Jack Fritscher, the only leather fashion pieces you need to become a leather daddy are a vest, a belt, and boots. However, the leather subculture is diverse and multifaceted, and individuals may choose to express their identity in different ways. Some participants associate leather culture with BDSM practices and its many subcultures, while others simply enjoy the sensory experience of leather.

Its important to note that the leather subculture is a consensual and respectful community that values communication, safety, and consent. The community is open to individuals of all genders, sexual orientations, and backgrounds who share a common interest in leather and BDSM practices.
