The Landtag of Saxony, also known in English as the Saxon State Parliament, is the legislature of the Free State of Saxony, one of Germany's sixteen states. It is responsible for legislation, control of the government, and electing some state officials. The Landtag has existed in various forms since 1831, but the current body was established during German reunification in 1990. The Landtag is directly elected and has a term of five years.

A Landtag is generally the legislative assembly or parliament of a federated state or other subnational self-governing entity in German-speaking nations. It is usually a unicameral assembly exercising legislative competence in non-federal matters.
