The Constitutional Democratic Party of Japan (立憲民主党, Rikken-minshutō; CDP or CDPJ) is a liberal political party in Japan. It is the primary centre-left party in Japan, and as of 2024 is the second largest party in the National Diet behind the ruling Liberal Democratic Party (LDP).

It was founded in October 2017 as a split from the Democratic Party ahead of the 2017 general election. In late 2020, the party was re-founded following a merger with majorities of the Democratic Party For the People and the Social Democratic Party as well as some independent lawmakers.

The party's platform supports raising the minimum wage, expanded welfare policies, the legalization of same-sex marriage, increased gender equality, renewable energy policies, decentralization, a multilateral foreign policy, the revision of the U.S.–Japan Status of Forces Agreement, tax reform and electoral reform. The party strongly opposes efforts to amend the Japanese Constitution to reinterpret Article 9 or codify the status of the Japan Self-Defense Forces and also opposes nuclear power.
