The 2018 Rugby Football League Championship is a rugby league football competition played primarily in the United Kingdom, one tier below the first tier Super League. The 2018 season is the fourth to consist of the Super 8s structure combining the Championship and Super League three-quarters of the way through the season. New sponsors for the league were announced in January 2018, and the league will be known as the Betfred Championship until the end of 2019. The bookmakers, Betfred, extended their sponsorship of rugby league to include the Championship and League 1 as well as Super League.
