Syringa komarowii is a species of lilac native to central China, commonly called nodding lilac. It is native to the Provinces of Gansu, Hubei, Shaanxi, Sichuan, Yunnan.

It is a shrub growing to 3–6 m tall, with erect branches. The leaves are oval-oblong, 5–19 cm long and 2–7 cm broad. The flowers are fragrant and range in colour from pink to mauve, sometimes with a white base; they are produced in early summer on panicles 4–25 cm long and are attractive to bees, butterflies, and birds. The panicles often hang limply, which is how the plant got its common name; the clusters look as though they are nodding.

There are two subspecies:

• Syringa komarowii subsp. komarowii C.K.Schneid.
• Syringa komarowii subsp. reflexa (C.K.Schneid.) P.S.Green & M.C.Chang.
