Giovanni Battista Gisleni (1600 – 3 May 1672) was an Italian Baroque architect, stage designer, theater director, singer, and musician at the Polish-Lithuanian royal court. Gisleni was born and died in Rome. He served three Polish kings of the Vasa dynasty: Sigismund III, Władysław IV and John II Casimir, during the years 1630–1668.
