Chen Li-an (Chinese: 陳履安; pinyin: Chén Lǚ'ān; born 22 June 1937 in Qingtian, Zhejiang, Republic of China), sometimes spelled Chen Lu-an, is a Taiwanese electrical engineer, mathematician and former politician.

He was the president of the Control Yuan from 1993 to 1995.

While he still considered the Kuomintang a "rotten party", Chen endorsed the KMT candidate Lien Chan in the 2000 ROC presidential election, believing that Lien was unlike the rest of the Kuomintang.

[1] In January 2001, Chen re-joined the Kuomintang, because he thought both the party and Taiwan needed him.
