List of M Countdown Chart winners (2016)

The M Countdown Chart is a record chart on the South Korean Mnet television music program M Countdown. Every week, the show awards the best-performing single on the chart in the country during its live broadcast.

In 2016, 36 singles achieved a number one on the show and 27 music acts were awarded first-place trophies. Six songs collected trophies for three weeks and achieved a triple crown: "Daddy" by Psy, "Dumb & Dumber" by iKon, "Rough" and "Navillera" by GFriend, "Cheer Up" by Twice, and "Monster" by Exo. No release for the year earned a perfect score, but "Monster" acquired the highest point total on the June 23 broadcast with 10,849 points.
