Zac Brian Meakin (born 18 November 2006) is a British-Ukrainian racing driver set to compete for Greystone GT in International GT Open.

Career Meakin stepped up to car racing in 2021, joining Raceway Motorsport to compete in the Ginetta Junior Championship. Spending two seasons in the series, Meakin scored a lone podium at Thruxton in his sophomore season, in which he drove for Preptech UK on his way to 11th in points. The following year, Meakin switched to GT4 competition as he joined Team Parker Racing in the British GT Championship. Starting off with a Porsche Cayman, Meakin took pole at Silverstone as the grid was set by FP2 times, and scored a best result of sixth at Oulton Park as he ended the year 14th in points after switching to a McLaren Artura mid-season.

Staying in GT4 competition for 2024, Meakin joined Elite Motorsport to race in the GT4 Winter Series alongside Tom Lebbon. After taking his maiden win in car racing at Estoril, Meakin won at Jerez, before taking his fourth win of the season at Valencia. Meakin took a final win at Barcelona on his way to third in points. For the rest of the year, Meakin returned to the GT4 class of the British GT Championship, joining Optimum Motorsport for his sophomore season alongside Jack Brown. Taking his first win of the season at Silverstone, Meakin took further wins at Donington Park, Snetterton and Brands Hatch to clinch the GT4 title at season's end. At the end of 2024, Meakin made his International GT Open debut at Monza for Optimum Motorsport alongside Mikey Porter.

Meakin returned to International GT Open the following year, returning to Optimum Motorsport alongside Porter for his first full-season in the series. In the season-opening round at Algarve, Meakin took his maiden series podium in race two by finishing second, a feat he repeated at the Hungaroring and Le Castellet to end the year eighth in points. During 2025, Meakin made a one-off appearance in the GT4 European Series for RAFA Racing by Race Lab at Spa, replacing Julius Dinesen in the team's No. 81 entry. Meakin also made his debut in the GT World Challenge Europe Endurance Cup for Greystone GT at Barcelona, finishing sixth in the Silver Cup on his debut.

After winning the 6 hours of Portimão with Greystone GT at the start of the year, Meakin continued with the team for the rest of the year to compete in International GT Open and the 24 Hours of Spa, as a new addition to the McLaren GT3 Junior Driver Programme.
