Juan Gerardo Guaidó Márquez is a Venezuelan politician who is the President of the National Assembly of Venezuela and is recognized as acting President of Venezuela by 54 governments. He is a member of the centrist social-democratic Popular Will party, and serves as a federal deputy to the National Assembly, representing the state of Vargas.

Guaidó took a public oath to serve as acting President on 23 January 2019, contesting the leadership of Nicolás Maduro. AP News reported that "familiar geopolitical sides" had formed in the 2019 Venezuelan presidential crisis, with allies Russia, China, Iran, Syria, and Cuba supporting Maduro, and the US, Canada, and most of Western Europe supporting Guaidó. His position on holding the acting presidency is based on an interpretation of Article 233 of the Constitution of Venezuela. The Supreme Tribunal of Justice (TSJ) rejected the National Assembly decisions, while the Supreme Tribunal of Justice of Venezuela in exile welcomed him as acting president.

Shortly after Guaidó became President of the National Assembly, he was briefly detained by authorities. He has also been prohibited from leaving the country, has had his assets frozen, is the subject of a probe into accusations that he helped foreign countries interfere in internal matters, and faces threats and intimidation from the Maduro administration in Venezuela. He has launched Plan País (a plan for the country), an amnesty law for military personnel and authorities who help to restore constitutional order, supported attempts to deliver humanitarian aid to the country, gained control of overseas assets, and appointed diplomats recognized by other countries. As of March, more than 80% of Venezuelans support him in polls as acting president, and he has an overall approval rating of 61%. He was named to Time magazine's list of 100 most influential people in the world for 2019.
