The 2023 Ambetter Health 200 was the 18th stock car race of the 2023 NASCAR Xfinity Series, and the 29th iteration of the event. The race was held on Saturday, July 15, 2023, in Loudon, New Hampshire at New Hampshire Motor Speedway, a 1.058 miles (1.703 km) permanent oval shaped racetrack. The race was originally scheduled to be contested over 200 laps, but was extended to 206 laps due to a NASCAR overtime finish. John Hunter Nemechek, driving for Joe Gibbs Racing, would put on a dominating performance, leading a race-high 137 laps, and winning the race after leading when the caution came out on the final lap. This was Nemechek's sixth career NASCAR Xfinity Series win, and his fourth of the season.[1] To fill out the podium, Chandler Smith, driving for Kaulig Racing, and Austin Hill, driving for Richard Childress Racing, would finish 2nd and 3rd, respectively.
