Yaroslav Vasylovych Pstrak (Ukrainian: Яросла́в Васи́льович Пстрак; 24 March 1878, Hvizdets - 16 March 1916, Kharkiv) was a Ukrainian painter, illustrator and graphic artist.

Later, he executed numerous church paintings, often working together with Osip Kurilas [uk]. Fromm 1903 to 1907, he lived in small Hutsul villages; painting scenes from the folk culture and people in native costume, as well as preserving examples of traditional architecture. He also began to illustrate works of literature by, among others, Gogol and Ivan Franko. he returned to Kolomyia on several occasions between 1909 and 1913. After that, he resumed his work as a portrait painter. His last known works were a series of mythological scenes painted in 1915.

However, World War I had interrupted his work to the point that he sank into poverty, which undermined his health. By late 1915, an unspecified nervous disorder, combined with starvation, led him to seek care at a military hospital in Kharkiv. He died there in the Spring of 1916.

In the 1910s and 1920s, postcards were very popular in Ukraine. From 1912 to 1914 the publisher, Grigoriy Hanulyak [uk], alone produced more than 120 designs; most of them based on paintings by Pstrak.^[1] Today, as a result, many of his works are better known, or only known, in their postcard form, rather than the originals.
