Hú Guāngdà 胡光大 (lifedates not recorded; fl. early 14th century, c. 1315). Son of 胡震 (Hú Zhèn, fl. 1305, of Lúshān shēnxī).

Within the Kanripo corpus he is the posthumous compiler of KR1a0075 Zhōuyì yǎn yì 周易衍義. His father Hú Zhèn died c. 1305 with the manuscript almost-finished; ten years later (c. 1315) Hú Guāngdà undertook the final compilation and editorial-arrangement to bring the work to publication. His shí yǔ 識語 (recognition-note, preserved at the back of his father’s auto-preface in the Sìkù base) records the death-bed scene where his father committed the unfinished manuscript to his care.

CBDB has no Yuán-period Hú Guāngdà entry under that name (the only CBDB Hú Guāngdà entry, id 647570, is Qīng-period).
