Constantin Alexandrovich Westchiloff (1877, St. Petersburg – 1945, New York) was a Russian-American impressionist painter. In 1898, he began studying at the Russian Academy of Art in St. Petersburg under Ilya Repin. In 1922, Westchiloff emigrated from the Soviet Union. In the following years, he lived in Italy and France until he finally immigrated to the United States in 1935, settling in New York. Throughout his artistic career, Westchiloff painted impressionist-style paintings varying from maritime landscapes and harbour scenes to rural genre scenes.
