In this article, the authors reflect on the unique role and purpose of key informants in community-engaged research. Taking a critical social science perspective, they consider the value and challenges involved in selecting and relying on key informants to represent the community and its perspectives. They offer insight into how community-engaged researchers can ensure that the key-informants in their own work will represent insider community perspectives and help identify and support community priorities.
