The 1962–63 Rheinlandliga was the 11th season of the highest amateur class of the Rhineland Football Association under the name of 1.
It was the seventh and final season in which the league played with two game divisions, East and West.
Beginning in the 1974–75 season, the league played a role as a sub-team to the newly introduced 2.
A relegation round was not played that year, since the former II Division was replaced to create the Regional League South.
For the coming 1963/64 season, the descendant from the second amateur League was SSV Mülheim, as well as VfB Wissen, Germania Metternich and FV Engers from the II.
