Lǐ Gōnghuàn 李公煥 (fl. late Southern Sòng to early Yuán, ca. mid-13th c.), is known almost solely as the jiānzhù (interpolated-annotation) editor of KR4b0009 Jiānzhù Táo Yuānmíng jí 箋註陶淵明集 — the standard SòngYuán annotated edition of Táo Qián’s collection. His annotations gather the Sòng commentarial tradition (Sū Shì 蘇軾, Huáng Tíngjiān 黃庭堅, Sū Zhé 蘇轍, Sī Mǎ Wēngōng 司馬溫公, Jiāng Jūn 江君, Wú Yīn 吳因 and others) on each Táo poem and fù. The Yuán Cuìyánjīngshè 翠巖精舍 cutting is the SBCK base. No personal biographical record survives; his life dates are unknown and CBDB does not register him. The dating of his edition is conventionally placed in the late 13th century on internal evidence (he cites no Yuán-period sources but his text is preserved in a Yuán print). The edition itself is one of the three canonical SòngYuán annotation traditions of Táo (alongside Tāng Hàn 湯漢 1241 and the lost Hé Tàibǎo 何泰保).
