Lei Chen (Chinese: 雷震; Pinyin: Léi Zhèn; 1897- 1979) was an early leading figure in the movement to bring fuller democracy to the government of Taiwan, the non-Communist nationalist Republic of China.
Lei Chen helped found and produce the periodical Free China, published beginning in 1950. He was arrested in 1960 and charged with treason and jailed; the charges are widely regarded as having been falsified by the Taiwan government and its then-ruling party the Kuomintang in response to Lei Chen's criticisms.
He was eventually released in 1970, and died in 1979.
