Fabio Gaetaniello (born 25 August 1958 in Livorno) is a former Italian rugby union player and coach. He played as a centre.
He started his career at CUS Pisa, like his brother Fabrizio, who also would be an international player, where he played until 1977/78. He moved afterwards to Rugby Livorno 1931, being at their squad from 1978/79 to 1981/82. He had his debut at Italian Championship in 1978. He moved to Rugby Parma F.C. 1931, where he played from 1982/83 to 1987/88. Once again, he returned to Rugby Livorno 1931, his team from 1988/89 to 1993/94, where he finished his player career. Gaetaniello never won an important national title during his player days.
He had 30 caps for Italy, from 1980 to 1991, scoring 5 tries, 20 points on aggregate. His first game was at the 18-13 win over Spain, in Madrid, at 21 December 1980, for the 1980–81 FIRA Trophy, aged 22 years old. He was called for the 1987 Rugby World Cup, playing in three games, without scoring, and for the 1991 Rugby World Cup, playing in three games and scoring a try in the 30-9 win over the United States, in Otley, at 5 October 1991. That would be the second win and the best result to date of Italy at the competition. His last game came at the 21-31 loss to New Zealand, in Leicester, at 13 October 1991, aged 33 years old, as Italy exited competition at the 1st round.[1]
