Joshua Wong Chi-fung is a Hong Kong activist and politician. He served as secretary-general of the pro-democracy party Demosistō until it disbanded following implementation of the Hong Kong national security law on 30 June 2020. Wong was previously convenor and founder of the Hong Kong student activist group Scholarism. Wong first rose to international prominence during the 2014 Hong Kong protests, and his pivotal role in the Umbrella Movement resulted in his inclusion in Time magazine's Most Influential Teens of 2014 and nomination for its 2014 Person of the Year; he was named one of the "world's greatest leaders" by Fortune magazine in 2015.
In August 2017, Wong and two other democracy activists were convicted and jailed for their roles in the occupation of Civic Square at the incipient stage of the 2014 Occupy Central protests; in January 2018, Wong was convicted and jailed again for failing to comply with a court order for clearance of the Mong Kok protest site during the Hong Kong protests in 2014. He also played a major role in persuading U.S. members of Congress to pass the Hong Kong Human Rights and Democracy Act during the 2019–2020 Hong Kong protests.
