Tang Liang Hong (simplified Chinese: 邓亮洪; traditional Chinese: 鄧亮洪; pinyin: Dèng Liàng Hóng; born 1935) is a politician and lawyer from Singapore.
Tang stood as a candidate for the opposition Workers' Party in the Cheng San Group Representation Constituency at the 1997 general election. The Worker's Party team in the constituency was defeated by the team from the governing People's Action Party (PAP) by 45.2% of the votes to 54.8%.
During the election campaign, Prime Minister Goh Chok Tong accused Tang of being an anti-Christian and anti-Muslim Chinese chauvinist. After the election, Tang was sued for defamation by several of the PAP's leaders, who accused him of making statements during the campaign which unreasonably questioned their integrity. Tang fled to Australia soon after the election and has not returned to Singapore since then. The plaintiffs in the lawsuits obtained default judgements against Tang in all their suits.
Tang was born in 1935 to parents who came from agricultural backgrounds. He was one of eight children in his family. He started his formal education only at the age of 13, when he began attending Yeung Ching Primary School in 1949. He graduated from high school in 1957. He then began studying at Nanyang University in 1962, and moved to the University of Singapore the following year. He graduated in 1967 and joined the bar a year later at the age of 38.
