Political Concepts: A Critical Lexicon is an online journal of political theory based at The New School for Social Research, first published in 2012. The journal publishes short essays, from a range of disciplines within the humanities and social sciences, that aim to critically define a political concept. Political Concepts is also responsible for the annual academic graduate student conference of the same name, which also began in 2012 and follows a similar format, accepting papers that aim to define political concepts. In 2018, a selected edited volume of articles from the journal was published under the same name, Political Concepts: A Critical Lexicon.
