Datuk Wee Jeck Seng (黃日升; born 20 April 1964) is a Malaysian politician and is the Member of the Parliament of Malaysia for the Tanjong Piai constituency in the State of Johor. He is a member of the Malaysian Chinese Association (MCA) party in the Barisan Nasional coalition.
Wee was elected to federal Parliament in the 2008 election for the seat of Tanjong Piai. Wee was nominated for the seat by the MCA after it was vacated by the party's president Ong Ka Ting to contest the Kulai seat. Before Wee's election, he was Ong's political secretary, as well as a member of the Johor State Assembly.
Immediately after his election to Parliament, Wee was appointed as a Deputy Minister in the government of Prime Minister Abdullah Badawi with responsibility for Youth and Sports. He retained his appointment when incoming Prime Minister Najib Tun Razak reshuffled the Ministry in April 2009. However, he was dropped from the ministry in June 2010 following MCA leadership elections.
Wee was born on 20 April 1964 and his hometown is Pontian. He is married.
