Felix Legueu (12 August 1863 – 2 October 1939) was a French urologist and gynecologist born in Angers.
He was a clinical professor in Paris and a surgeon at Hôpital Necker. He was a member of the Académie de Médecine.
Legueu was a highly regarded surgeon involving genitourinary disorders. In 1913 he described a surgical technique concerning vesicovaginal fistulae (VVF). A VVF is an abnormal passageway between the bladder and vagina. Today, the Dittel-Forgue-Legueu operation is sometimes used for closure of vesicovaginal fistulae. This surgical procedure is named in conjunction with Drs. Dittel and Forgue. A few modern surgical instruments bear Legueu's name, such as the Legueu bladder retractor and the Legueu bladder spatula.
