The 2020 ARCA Menards Series East was the 34th season of the ARCA Menards Series East, a regional stock car racing series sanctioned by NASCAR. It began on February 10 at New Smyrna Speedway with the Skip's Western Outfitters 175, and concluded on October 11 at Five Flags Speedway with the Pensacola 200. 2020 marked the first season the series was known as the ARCA Menards Series East, after it was known as the NASCAR K&N Pro Series East for the previous ten years.

Sam Mayer entered the season as the defending champion, and won all but one race to score his second consecutive championship in the series.

When the season was put on hold due to the COVID-19 pandemic, drivers from all NASCAR series, including a few ARCA drivers, participated in the inaugural eNASCAR iRacing Pro Invitational Series during that time.
