2016 NASCAR K&N Pro Series West

The 2016 NASCAR K&N Pro Series West was the sixty-third season of the K&N Pro Series West. It began at Irwindale Speedway on March 19 and concluded at All American Speedway on October 15. Chris Eggleston entered the season as the defending drivers' Champion. Todd Gilliland won the championship, thirteen points in front of Ryan Partridge.

Gilliland also became the youngest champion in West Series and NASCAR history, winning the title at 16 years and 5 months. The record for youngest champion in all of NASCAR was broken by Sam Mayer's 2019 East Series championship when he was 16 years, 3 months, and 8 days. However, Gilliland remains to this day the youngest West Series champion.
