Iuliu Falb (14 December 1942 – 2009) was a Romanian fencer. He competed in the team foil events at the 1964, 1968 and 1972 Summer Olympics.
Falb took up fencing under the coaching of Andrei Altman at the local club "ÃÂFlacÃÂra RoÃÂieÃÂ", where he became friends with future teammate and Olympic champion Ion DrîmbÃÂ. He transferred in 1961 to CSA Steaua with coaches Constantin Panescu and Vasile Chelaru. He was national champion in 1965, 1966 and 1967. That same year, along with Ion DrîmbÃÂ, ÃÂtefan Ardeleanu, TÃÂnase MureÃÂanu and Mihai ÃÂiu, he earned Romania's first team world title in fencing with a gold medal in Montreal. He was named "master in sports" (Maestru al sportului) in 1966, then "honoured master in sports" (Maestru emerit al sportului) a year later.
After his retirement as an athlete, Falb became a fencing coach, working for several clubs and for the National Institute of Physical Education in Bucharest. He also served as a national and international referee.
