Rubens Gonçalves "Rubinho" Barrichello (born May 23, 1972 in São Paulo) is a Brazilian Formula One racing driver. Driving for the Brawn GP team, Barrichello finished third in the 2009 championship. He is racing for WilliamsF1 in 2010.
Barrichello has scored the fourth highest points total in Formula One history. Barrichello drove for Ferrari from 2000 to 2005, as Michael Schumacher's teammate, enjoying considerable success including finishing as championship runner-up in 2002 and 2004. Schumacher's retirement at the end of 2006 made Barrichello the most experienced driver on the grid, and at the 2008 Turkish Grand Prix he became the most experienced driver in F1 history. He is set to become the first driver to reach 300 Grand Prix entries and 300 starts in 2010. Assuming the season is trouble free, his 300th start will be achieved at the Japanese Grand Prix.
Both his father and paternal grandfather are also named Rubens, and Barrichello shares his father's birthday: May 23. Therefore, Rubens Barrichello was known as Rubinho (Portuguese for "little Rubens"), which has become his nickname.
