Constantin "Titi" Dumitrescu (born 14 March 1931) is a retired light-welterweight boxer from Romania. He won five consecutive national titles in 1955–1959 and a bronze medal at the 1956 Olympics.[2]
Dumitrescu took up boxing in 1946 under the guidance of his father George Dumitrescu.[1] He announced his retirement right after winning his last national title in 1959. On the next day he was hired as a boxing coach and kept that job until 1985, raising 80 national champions.[1] [3]
