The 1989 West Berlin state election was held on 29 January 1989 to elect the members of the 11th Abgeordnetenhaus of Berlin.

It fell by 8.7 percentage points and ended up with 37.7% of the votes just ahead of the SPD, which gained 4.9 percentage points to 37.3% under its lead candidate Walter Momper. Together with the Alternative List (AL), this resulted in a clear majority for a red–green coalition.
