Alon Day (Hebrew: אלון דאי, born November 4, 1991) is an Israeli professional stock car racing driver.

[3][4][5][6] His father, Avi Day, owns a geological-engineering company involved in mineral drilling, and his mother Maggi originally immigrated to Israel from France.

In 2012 Day's career transitioned to North America, where he signed to drive in the Firestone Indy Lights series with Belardi Auto Racing.

Day made six starts for the team before they amicably parted ways in June after qualifying at the Iowa Speedway.

[15] Also in 2016, Day was named one of the 11 members of the 2016–17 NASCAR Next program, which recognizes young successful drivers from around the world who are seeking to improve.

[16][9] Day was the first driver of NASCAR's European circuit (the Whelen Euro Series) to earn the honor.

[17] The effort was supported by Jewish Sarasota, Florida, environmental/waterfront property lawyer David Levin, who provided Day with $60,000 from his retirement account to fund the car.

[18][19][6] After qualifying 22nd, Day capitalized on the rainy conditions to enter the top ten, where he ran for most of the race before finishing 13th.

In September, Contreras Motorsports hired Day to make his Camping World Truck Series debut at the New Hampshire Motor Speedway, in which he finished 24th.

[25] Later in June, Day joined BK Racing for his Monster Energy NASCAR Cup Series debut in Sonoma Raceway's Toyota/Save Mart 350, driving the No.

[28] In mid-October, following a fourth-place finish at the second final of the NASCAR Whelen Euro race at Circuit Zolder, he became the first Israeli driver to win a NASCAR championship, clinching the 2017 championship title after only completing just the first lap, finishing the final standings 53 points ahead of defending and two-time series champion Anthony Kumpen.

On October 4, 2020, Day won his first EuroNASCAR contest of the season at Zolder and also assumed the points lead.
