Jan Brunon Bułhak (1876–1950) was an early 20th century photographer in Poland and present-day Belarus and Lithuania. A published theoretician and philosopher of photography, he was an exponent of pictorialism. He is best known for his landscapes and photographs of various places, especially the city of Vilnius (then in Poland, now in Lithuania). He was the founder of the Wilno Photoclub and Polish Photoclub, the predecessors of the modern Union of Polish Art Photographers (ZPAF), of which he was an honorary office-holder. He is also known as an ethnographer and folklorist.
