Kamenny Island Palace is a former imperial palace on the south-western promontory of Kamenny Island in St. Petersburg.
The Neoclassical edifice was commissioned in the 1770s by Catherine II of Russia for her son Paul. It has a portico of six Tuscan columns and a spacious cour d'honneur. The river front of the palace is broken by eight Doric columns. The residence was built under the general supervision of Yury Felten. The interiors were designed by Vincenzo Brenna in imitation of Piranesi's views of Rome. Jean-François Thomas de Thomon was responsible for renovating the garden. Giacomo Quarenghi updated the design after the work resumed.
Emperor Paul presented the palace to the former Polish king, Stanisław August Poniatowski. The palace's most famous tenant was Alexander I of Russia.
