Justin Sun (Chinese: 孙宇晨; pinyin: Sūn Yǔchén; born July 30, 1990) is a Chinese-born Kittitian crypto billionaire and businessman. He is the founder of TRON, a company that develops the TRON blockchain with the associated Tronix (TRX) cryptocurrency token, as well as USDD, a stablecoin issued by TRON DAO Reserve. Sun is also the owner of Rainberry (formerly BitTorrent Inc.), which developed the BitTorrent protocol and under Sun's leadership developed the BTT cryptocurrency token. Sun also owns the crypto currency exchanges Poloniex and HTX (formerly Huobi). Sun was Permanent Representative of Grenada to the World Trade Organization (WTO) in Geneva from 2021 to 2023.

As of 2025, Sun is estimated to have a net worth of US$12.5 billion, according to Bloomberg, which is largely held in cryptocurrency, including Tronix tokens (TRX), of which he owns the majority.

Sun's companies have been investigated by the U.S. Securities and Exchange Commission (SEC). After having formed business ties with Donald Trump, who became president in 2025, Sun's companies received more lenient treatment by the SEC.
