NIMBY (an acronym for the phrase "not in my back yard"),[1][2] or Nimby,[3] is a characterisation of opposition by residents to a proposed development in their local area. It carries the connotation that such residents are only opposing the development because it is close to them and that they would tolerate or support it if it were built farther away. In some cases, NIMBY opposition can be overcome through an open process and impact mitigation.[4] The residents are often called Nimbys, and their viewpoint is called Nimbyism.
