Sergio Savaro Giovanni Lanfranchi (Parma, 27 September 1925 – Barjols, 22 January 2000) was an Italian rugby union player and coach, active in France for most of his career as flanker, number 8 and lock.

Orphaned of both parents, after school he was a combatant in Piedmont for the Italian Resistance and,[1] returning to Parma after the war, he started to work and play rugby union for the local team in 1946.

[1] After winning the scudetto, he moved to France and established himself in Grenoble, becoming part of the local team which never had won a championship.

Having learned to play in all the forward positions and, sometimes as fly-half and centre,[1] he was between the most important players who led Grenoble to the 1953-54 French Rugby Union Championship played in Toulouse against Cognac, thanks to a try scored by Lanfranchi 20 minutes before the end of the match.

He played for Italy until he was 38 years old and for FC Grenoble until he was 40,[4] when he moved to Montceau-les-Mines[1] as player-coach,[5] alternating his career at Montchanin; it is not clear if his career ended in 1971 at age 46 or in 1973 at age 48 due to discordant sources,[5] however, it was in Montchanin that he definitively established; in 1978 he had a brief experience in Italy as coach for L'Aquila Rugby,[5] which soon terminated due to a lack of synchrony with the rugby environment of his home country.
