Félix Legueu (12 August 1863 – 2 October 1939) was a French urologist and gynecologist born in Angers.
Legueu was a clinical professor in Paris, a surgeon at Hôpital Necker and a member of the Académie de Médecine.
He specialized in genitourinary disorders. In 1913 he described a procedure for the closure of a vesicovaginal fistula, an abnormal passageway between the bladder and the vagina. That operation, today called the "Dittel-Forgue-Legueu operation", is also named after Drs. Leopold von Dittel (1815–1898) and Émile Forgue (1860–1943).
A few surgical instruments bear Legueu's name, such as the "Legueu bladder retractor" and the "Legueu bladder spatula".
Legueu died in his home from carbon monoxide poisoning.
