Marcelo Filippini (born 4 August 1967) is a former professional tennis player from Uruguay. In 1996, Filippini played what was longest known game in ATP Tour history at Casablanca, going to deuce 20 times with Alberto Berasategui in one game of a 6–2, 6–3 first round loss. The game lasted 28 minutes (24–22 in total points for Berasategui). Filippini's best performance at a Grand Slam event came at the French Open in 1999, where he reached (as a qualifier without dropping a set) the quarterfinals, defeating Laurence Tieleman, Martin Damm, Vince Spadea and Greg Rusedski before being knocked-out by eventual champion Andre Agassi. He also reached the quarterfinals of the 1993 Rome Masters.
