2019 NASCAR K&N Pro Series East

The 2019 NASCAR K&N Pro Series East was the 33rd season of the K&N Pro Series East, a regional stock car racing series sanctioned by NASCAR. It began with the New Smyrna 175 at New Smyrna Speedway on February 11 and concluded with the General Tire 125 at Dover International Speedway on October 4. General Tire took over the position as the official tire supplier of the series from Goodyear. Sam Mayer was crowned the series champion, becoming the youngest champion in series history, at 16 years, 3 months, 8 days, topping the previous record set by Todd Gilliland after he won the 2016 title. Tyler Ankrum entered the season as the defending drivers' champion, but he did not defend his championship because he moved up to the Truck Series full time in 2019.

This was the last season of the series before it became an ARCA series in 2020 as part of the unification of the NASCAR K&N Pro Series East and West and the ARCA Menards Series.
