Ecclesiastical peerages (Thai: สมณศักดิ์; RTGS: samanasak; literally "ecclesiastical dignity") have traditionally been given to ordained members of the Thai sangha, the community of the Buddhist monks of Thailand.

Each ecclesiastical peer holds a rank (Thai: ยศ; RTGS: yot) and a title (Thai: ราชทินนาม; RTGS: ratchathinnanam). For example, Phra Dharma Kośācārya (Thai: พระธรรมโกศาจารย์; RTGS: Phra Tham Kosachan) is the title of a monk holding the rank of phra rachakhana (Thai: พระราชาคณะ) in the dharma class. In addition to an ecclesiastical peerage, a monk may also be known by a layname (name as a layperson) and a dharmic name.

Holders of certain ranks are given fans of rank [th] (Thai: พัดยศ; RTGS: phat yot).
