Wú Mì 吳秘 (fl. 1050s) was a Northern Sòng official and Confucian commentator who rose to Sīfēng yuánwài láng 司封員外郎 in the central administration. Sīmǎ Guāng’s preface to the Yángzǐ Fǎ yán jí zhù names him together with Sòng Xián as the two recent commentators on the Fǎ yán whose work was independently extant when Sīmǎ undertook the integrating jízhù (collected commentary), the older Lǐ Guǐ and Liǔ Zōngyuán strata being only partial. The four-stratum collation — Lǐ Guǐ, Liǔ Zōngyuán, Sòng Xián, Wú Mì — formed the base on which Sīmǎ added his own remarks, and the joint product is the Fǎ yán jí zhù of KR3a0009. CBDB has two homonyms named 吳秘 (ids 93228, 95952), neither with confirmed dates corresponding to the Fǎ yán commentator.
