William Venturini (born April 7, 1976) is an American professional stock car racing driver and team owner.

He currently co-owns Venturini Motorsports, a racing team that competes in the ARCA Menards Series, along with his father, Bill.

He drove a race for Bill Egbert in the season finale at Atlanta Motor Speedway, finishing 32nd due to a driveshaft issue.

In 1997, he joined Ed Rensi Racing to run a nine-race schedule, earning his best finish of 5th at Charlotte Motor Speedway.

He would respectively finish inside the top five in point standings for the next two years, along with earning a pole at Lake Erie Speedway in 2003.

On May 6, 2023, during an interview with motorsport news website Frontstretch, Venturini revealed that he would return to the driver's seat for the first time in 16 years, running the ARCA Menards Series East race at Flat Rock Speedway.

Venturini attempted to make his NASCAR Craftsman Truck Series debut in 1999, racing at Martinsville Speedway for his family team, but would fail to qualify for the event.

Venturini would later be known for helping his team become one of the most premier driver development programs in the ARCA circuit, collecting over 50 wins in the series, including a championship in 2019.

On lap 57 of the race, Drew Dollar made contact with Heim exiting turn 4, causing both of them to hit the outside wall, and spin through the infield grass.
