Zhāng Xiǎn 張顯 (fl. Jìn) is an Eastern Jìn 東晉 figure known almost exclusively from the title-attribution on his lost Xīyán lùn 析言論 (preserved in Tàipíng yùlǎn, Yìwén lèijù, Ěryǎ shìwén, and Lù shǐ). No biography survives in the standard histories. His exact birth and death years are not preserved; he is conventionally assigned to the Eastern Jìn period on the basis of the Suí shū jīngjí zhì placement. CBDB has no entry.
In the Kanripo corpus he is the attributed author of KR3a0155 Xīyán lùn 析言論.
