Yen Kuan-heng Kuomintang The 2013 Taichung legislative by-election was held in Taiwan on 23 January 2013 for the Taichung City Constituency II after the former legislator Yen Ching-piao was disqualified for corruption.

Yen, who joined the pan-blue Non-Partisan Solidarity Union in 2004, was re-elected three times in 2004, 2008 and 2012.

DPP officials accused the authorities of trying to discourage other candidates to run, while the Central Election Commission officials said they considered holding the election before Lunar New Year holiday such that new legislator can be sworn in at the beginning of the new session.
