The 1997 Hamburg state election was held on 21 September 1997 to elect the members of the 16th Hamburg Parliament. The incumbent government of the Social Democratic Party (SPD) and Statt Party under First Mayor Henning Voscherau was defeated as Statt lost all its seats. The SPD subsequently formed a coalition with the Green Alternative List (GAL). Voscherau declined to run for re-election as First Mayor due to the SPD's poor performance, and fellow SPD member Ortwin Runde succeeded him.
