非政府部门公共机构（英语：non-departmental public body，缩写：NDPB）是英国内阁、财政部、苏格兰政府和北爱尔兰行政院采用的一种半官方机构分类方式，它不是政府部门的组成部分，但却行使政府部门的职权。其部长最终还是要向英国国会负责。

现在总共有四种类型的非政府部门各公共机构。但国民保健服务和BBC等公共广播不在此列。 到2009年3月为止，英国共有将近800个非政府部门公共组织。

In the United Kingdom, non-departmental public body (NDPB) is a classification applied by the Cabinet Office, Treasury, the Scottish Government and the Northern Ireland Executive to quangos (quasi-autonomous non-governmental organisations). NDPBs are not an integral part of any government department and carry out their work at arm's length from ministers, although ministers are ultimately responsible to Parliament for the activities of bodies sponsored by their department.
