Khosrow Hassanzadeh is one of the Iranian contemporary painters. The artist's name became popular with a collection of paintings entitled War. His artworks can not be placed in a particular style, but Hassanzadeh has been mentioned with titles such as the neo-pop traditionalist artist.
He studied painting in Mojtam-e-Honar. After that, he studied Persian literature and received his master's degree from Islamic Azad University. At the same time, he studied painting for two years under supervision of Aydin Aghdashloo.
In 1991, Hassanzadeh exhibited thirteen paintings for the first time in Tehran's Jamshidieh Park. Seven years later, he participated in a layout project for a dilapidated house called "Experience 77". His first foreign exhibition was held in 1999 in the collection entitled "Life, War, and Art: A Painting by Khosrow Hassanzadeh" in the center of art in London. In 2001, he received a scholarship in Paris and went to France to continue his studies. Hosseinzadeh's paintings have also been exhibited in art centers in Beirut, Zagreb, Dubai, and Amsterdam. His artworks have also found their way to prestigious world art centers such as the British Museum and the Tehran Museum of Contemporary Art.
 Pakbaz writes about the artist's three different periods: "Khosrow Hassanzadeh became famous for his memoirs of the Iran-Iraq war. Images of the slain in white shrouds, pierced helmets, etc., were often drawn on paper with ink and acrylic, and inscriptions were added. In the early 2001s, he created the Terrorist series that was an implicit protest against Western labeling of Muslims: a single image of himself and his family, printed on canvas in large-scale silhouettes of imams and writings, was added by using the Silk Screen method. "Recently, he has been using the same method in creating artworks on the subject of wrestlers and heroes." He passed away in Tehran in July 2023.
