2023–24 Scottish League Championship

The 2023–24 Scottish League Championship, or 2023–24 Tennents League Championship for sponsorship reasons, is the 48th season of formal domestic rugby union leagues in Scotland.

The season began on September 2, 2023, with defending champions Hawick RFC playing Glasgow Hawks at their home pitch of Mansfield Park. Kelso RFC was promoted to the premier league to take the place of Glasgow Hutchesons Aloysians, who were relegated to National Division One.

Currie won their third Championship title and first in over 14 years, with Hawick finishing as runners up after a repeat of last season's final. Jed-Forest were relegated after finishing bottom.

The format was altered slightly from last season, with all Divisions having 10 teams as opposed to 2022-23 in which all but the Premiership division had 12 teams. In addition, a new fourth National Division was established with the bottom three teams competing in it being relegated to their respective Regional League Division 1.
