2016–17 WRU Division 1 East

The 2016–17 WRU National Division 1 East was the third season of the new format of the WRU National Leagues. Previously, League 1 was the second tier of club rugby in Wales but since the creation of the WRU National Championship, League 1 is now the third tier. The league was won by Rhydyfelin and the bottom two clubs relegated to League 2 East were Nantyglo and Senghenydd.

Structure
Each team in the league will play each other twice on a home and away basis for a total of 22 matches played each. Points will be awarded in accordance to the standard scoring system in rugby union - 4 points for a win, 2 points for a draw and 0 for a loss. Teams will also be awarded 1 additional bonus point for scoring 4 or more tries in a match or losing by 7 points or less in a match. The team with the most points at the end of the season will be declared the winners. This season sees the return of the promotion play-off whereby the winning club will enter a play-off with the winner of Division 1 East Central to determine which club is to be promoted to the 2017-18 WRU Championship.
