The 1992 Schleswig-Holstein state election was held on 5 April 1992 to elect the members of the Landtag of Schleswig-Holstein.

The incumbent Social Democratic Party (SPD) government led by Minister-President Björn Engholm narrowly retained its majority by a margin of one seat.

The major change of the election was the entry of the national conservative German People's Union to the Landtag.

The Free Democratic Party also re-entered the Landtag, while The Greens failed to surpass the threshold by a margin of 0.03%.
