The 2023 ARCA Menards Series East was the 37th season of the ARCA Menards Series East, a regional stock car racing series sanctioned by NASCAR in the United States. The season began on March 25 with the Pensacola 200 at Five Flags Speedway and ended on September 14 with the Bush's Beans 200 at Bristol Motor Speedway.
Sammy Smith, the defending series champion in 2021 and 2022, moved up to the NASCAR Xfinity Series to run full-time for Joe Gibbs Racing in 2023 and therefore did not return to run full-time in the ARCA Menards Series East and defend his title. William Sawalich replaced him in the No. 18 car in 2023, which went back to being owned by JGR after being owned by Kyle Busch Motorsports in 2022.[1] At the conclusion of the season, Sawalich clinched the ARCA Menards Series East championship.[2]
