Shàn Nánshān 單南山 (fl. late 18th / early 19th c. 清), late-Qīng obstetrical specialist. Documented in Chinese-medicine bibliographic literature as author of two coordinated works on pregnancy and childbirth:
- Pánzhū jí tāichǎn zhèngzhì 盤珠集胎產症治 (KR3ei049) — three-juǎn systematic obstetrical treatise.
