Yong Saetae (Thai: หยง แซ่แต้; Chinese: 鄭鏞, Teochew: Dên Iong; ?–?) was a Chinese merchant and the father of the Siamese king Taksin. In Vietnamese record, he was called Trịnh Yển (鄭偃).
His birth name was Dên Dag (Chinese: 鄭達; pinyin: Zhèng Dá). Born in Chenghai County, Shantou, Guangdong Province, Qing China. It was said that he was a broad-minded and unconventional man. His fellow countrymen did not like him, and called him Pai Gian Dag (痞囝達 or 歹子達, lit. "Dag, the ruffian" in Teochew). During the Yongzheng Emperor's reign, he came to Siam to do business, and became rich, and changed him name to Yong Saetae. Later, he became a tax-collector, and married Nok-lang (later Princess Phithak Thephamat), who later gave birth to Taksin the Great.
